DESCRIPTION:Speakers: William Dix (Univ Melbourne)\nThe SABRE (Sodium-iodi
 de with Active Background REjection) experiments aim to detect an annual r
 ate modulation from dark matter interactions in ultra-high purity NaI(Tl) 
 crystals. The SABRE south experiment is located at the Stawell Underground
  Physics Laboratory (SUPL)\, Australia\, the first deep underground labora
 tory in the Southern Hemisphere\, due to be completed in late 2021. SABRE 
 South is designed to disentangle seasonal or site-related effects from the
  dark matter-like modulated signal first observed by DAMA/LIBRA in the Nor
 thern Hemisphere. It is a partner to the SABRE North effort at the Gran Sa
 sso National Laboratory (LNGS).\n\nSABRE South is instrumented with ultra 
 high purity NaI(Tl) crystals immersed in a linear alkyl benzene based liqu
 id scintillator veto\, further surrounded by passive steel and polyethylen
 e shielding and a plastic scintillator muon veto.  The SABRE South experim
 ent is under construction\, and will be commissioned from late 2021 to ear
 ly 2022. In this presentation we will present the final design of SABRE So
 uth\, the status of its construction\, its expected background\, and its s
 ensitivity to a DAMA/LIBRA like modulation. We will also present recent qu
 enching factor measurements of sodium nuclear recoils in NaI(Tl) crystals 
 measured with the ANU Heavy Ion Accelerator Facility\, and a report on the
  status of SUPL.\n\nhttps://indico.ific.uv.es/event/6178/contributions/159

DESCRIPTION:Speakers: David Cintas González (Universidad de Zaragoza)\nTe
 sting the DAMA/LIBRA annual modulation result independently of dark matter
  particle and halo models has been a challenge for twenty years. Using sam
 e target material\, NaI(Tl)\, is required and presently two experiments\, 
 ANAIS-112 and COSINE-100\, are running for such a goal. However\, a precis
 e knowledge of the detector response to nuclear recoils is mandatory becau
 se this is the channel where the dark matter signal is expected. The emitt
 ed light is quenched with respect to the gamma-calibrated energy by a fact
 or that has to be measured experimentally. However\, current quenching fac
 tor measurements show a disagreement within the energy region of interest 
 for dark matter searches. To disentangle whether this discrepancy is due t
 o intrinsic differences in the light response among different NaI(Tl) crys
 tals\, or has its origin in unaccounted for systematic effects will be key
  in the comparison among the different experiments. We present measurement
 s of the quenching factors for several small NaI(Tl) crystals performed in
  the same experimental setup to control systematics. Nuclear recoils were 
 produced by quasi-monoenergetic neutrons\, and triggering was done by the 
 scattered neutron interacting in one of the 17 liquid scintillator backing
  detectors placed at different angles from the NaI(Tl) crystal. This trigg
 ering avoids threshold effects that could have affected some of the previo
 us experimental results. In this talk\, we will present the results of our
  experiment and a comparison with those available in the literature. We wi
 ll also analyze their effect on the annual modulation interpretation.\n\nh

DESCRIPTION:Speakers: Nicolás Avalos (CONICET)\nThe Dark Matter Daily Mod
 ulation experiment (DMSQUARE) seeks for dark matter interactions with a Sk
 ipper CCD. It is currently running at surface level in Bariloche\, Argenti
 na\, and will be moved to a shallow underground site at Sierra Grande\, Ar
 g\, in September 2021. The low threshold achieved by Skipper CCDs allows t
 o search for electron recoil events with an ionization energy down to 1.2 
 eV. In order to extract a potential dark matter signal from noise at the s
 ingle electron level\, we propose to search for a diurnal modulation of ev
 ents\, resulting from the potential interaction of the dark matter wind th
 rough the Earth. Depending on the model\, mass and cross-section\, this mo
 dulation can be maximum at 40deg of latitude in the Southern Hemisphere\, 
 where DMSQUARE is operated. In this talk we will present the experiment\, 
 report preliminary results with Skipper CCDs taking data at surface level 
 and comment on future prospects for the experiment.\n\nhttps://indico.ific

DESCRIPTION:Speakers: Cyprien Beaufort (LPSC / CNRS)\nThe detection of a d
 ark matter (DM) particle would deeply contribute to the understanding of t
 he Universe and would shine light on new Physics. The WIMP is an extensive
 ly studied DM candidate that would induce nuclear recoils inside a detecto
 r. The largest direct projects searching for WIMPs will soon reach the “
 neutrino floor”\, a boundary beyond which a WIMP signal cannot be distin
 guished from the irreducible background due to neutrinos. The only known p
 rinciple to overpass this background is to measure the direction of the in
 duced recoils and to correlate it with the expected incoming direction of 
 the WIMPs. This is the principle of directional detection. \n\nIn this tal
 k we will introduce MIMAC\, a directional detector that measures simultane
 ously the energy of a particle and reconstructs its track in 3D in an adap
 table energy range [150 eV \, 30 MeV]. MIMAC is a gaseous µ-TPC in which 
 one can adapt the experimental conditions (target mass\, spin\, pressure\,
  etc.) to particular DM candidates phenomenology.\n\nWe will focus on the 
 study of directionality in the keV-range for which there is a lack of expe
 rimental data. In this low energy region\, the lengths of the WIMP-induced
  nuclear recoils lie in the sub-millimeter range. We will show that the di
 ffusion of the primary electrons\, usually considered as a limiting phenom
 enon\, improve our directional performances for sub-millimeter tracks! Mea
 suring low-energy recoils implies to operate at high-gain\, for which many
  ions are produced in the avalanche process. We have developed SimuMimac\,
  a simulation tool that investigates the influence of the ions on the sign
 al formation and the 3D reconstruction. SimuMimac agrees with the measurem
 ents and shines light on possible deconvolutions of the signal induced by 
 the ions. \n\nLow-energy electrons are of interest to understand the backg
 round but also\, for instance\, to search for Axion-Like Particles. In thi
 s talk we will present 3D tracks of electrons down to 150eV. At these ener
 gies\, only a few primary electrons are generated by the ionization proces
 s. We will show that MIMAC is sensitive to the fluctuation of the number o
 f primary electrons and that we can use this phenomenon to determine the g
 ain per primary electrons.\n\nhttps://indico.ific.uv.es/event/6178/contrib

  is a strong need to test the long standing DAMA positive observation of a

  sensitivity to the annual modulation signal\, compared to the present tec
 hnology\, by lowering the detection energy threshold\, making it possible 
 for the first time to observe sub-keV recoils. \nThis can be achieved by r
 eading the scintillation light from the NaI(Tl) crystals with arrays of Si
 licon PhotoMultipliers (SiPM)\, and placing the detectors in a cryogenic e
 nvironment. \nIndeed\, SiPMs feature lower dark noise than photomultiplier

DESCRIPTION:Speakers: Florian Reindl (HEPHY (ÖAW) & TU Wien\, Vienna)\nTo
 day\, the situation in direct dark matter detection is puzzling: The DAMA/
 LIBRA experiment observes an annual modulation signal at high statistical 
 significance and fitting to the expectation of a cold dark matter halo in 
 the milky way. However\, in the so-called standard scenario on dark matter
  halo and dark matter interaction properties\, the DAMA/LIBRA signal contr
 adicts the null-results of numerous other experiments.\n\nCOSINUS aims for
  a model-independent cross-check of the DAMA/LIBRA signal. To be immune to
  potential dependencies on the target material\, COSINUS will use NaI targ
 et crystals\, the same material as DAMA/LIBRA. Several experimental effort
 s with NaI targets are planned or already ongoing. COSINUS is the only exp
 eriment operating NaI as a cryogenic detector\, which yields several disti
 nctive advantages: Discrimination between electronic interactions and nucl
 ear recoils off sodium and iodine on an event-by-event basis\, a lower nuc
 lear recoil energy threshold\, and a better energy resolution.\n\nIn this 
 contribution\, we will sketch the current status of the COSINUS experiment
 \, from the development of the cryogenic NaI detectors to the construction
  of the experimental facility at the LNGS underground laboratory.\n\nhttps

DESCRIPTION:Speakers: Iván Coarasa (Universidad de Zaragoza)\nANAIS (Annu
 al modulation with NaI(Tl) Scintillators) is a direct dark matter detectio
 n experiment aiming at the confirmation or refutation of the DAMA/LIBRA po
 sitive annual modulation signal in the low energy detection rate\, using t
 he same target and technique. ANAIS−112\, located at the Canfranc Underg
 round Laboratory in Spain\, is operating an array of 3×3 ultrapure NaI(Tl
 ) crystals with a total mass of 112.5 kg since August\, 2017. The trigger 
 rate in the region of interest (1-6 keV) is dominated by non-bulk scintill
 ation events. In order to discriminate these noise events from bulk scinti
 llation events\, robust filtering protocols have been developed. Although 
 this filtering procedure works very well above 2 keV\, the measured rate f
 rom 1 to 2 keV is about 50% higher than expected by our background model\,
  and we cannot discard non-bulk scintillation events as responsible of tha
 t excess. In order to improve the rejection of noise events\, a Boosted De
 cision Tree (BDT) has been developed and applied. With this new PMT-relate
 d noise rejection algorithm\, the ANAIS−112 background between 1 and 2 k
 eV is reduced by almost 30%\, leading to an increase in sensitivity to the
  annual modulation signal. In this talk\, the reanalysis of the three year
 s of ANAIS−112 data taking with this technique will be presented.\n\nhtt

DESCRIPTION:Speakers: Matthew Stukel (Queen's University)\nPotassium-40 (K
 -40) is a long-lived\, naturally occurring radioactive isotope. The decay 
 products are prominent backgrounds for many rare event searches\, especial
 ly those involving NaI-based scintillators (ex. DAMA\, ANAIS-112\, COSINE-
 100\, SABRE\, COSINUS etc.). The branching ratio of the electron capture d
 irectly to the ground state of Argon-40 has never been experimentally meas
 ured and presents an unknown background directly in the 2-6 keV energy reg
 ion. This is the same region where the DAMA/LIBRA experiment observes thei
 r unique annual modulation. Knowledge of this branching ratio can place co
 nstraints on the allowed modulation fraction observed by the DAMA experime
 nt. In addition\, this branching ratio has important implications for nucl
 ear physics and geochronology. KDK (Potassium (K) Decay (DK)) is an intern
 ational collaboration dedicated to the measurement of this branching ratio
 . The experiment is performed using a silicon drift detector with a therma
 lly deposited\, enriched K-40 source inside the Modular Total Absorption S
 pectrometer (MTAS\, Oak Ridge National Laboratory). MTAS is a large NaI de
 tector whose high gamma-ray efficiency enables the proper discrimination b
 etween ground and excited state electron capture events. This setup has be
 en characterized in terms of energy calibration and dead time\, and a tagg
 ing efficiency of 97.89(6) % has been demonstrated (arXiv:2012.15232 submi
 tted to NIM). We report on the analysis method and sensitivity for a 44-da
 y K-40 physics run.\n\nhttps://indico.ific.uv.es/event/6178/contributions/

DESCRIPTION:Speakers: Xinran Li (Lawrence Berkeley National Laboratory)\nL
 iquid argon (LAr) is one of the most promising targets for the search of W
 IMP-like dark matter. LAr dual-phase time projection chamber (LAr TPC) is 
 a leading technology\, able to detect both the scintillation and ionizatio
 n signals. The correlation in the two signal channels provides a possible 
 handle to measure the recoil direction of the nuclei: if confirmed\, this 
 would allow inferring the incident direction of potential dark matter cand
 idates.\n\nPrevious work from SCENE resulted in a hint of the existence of
  a directional effect\, which can potentially pave the way for a tonne sca
 le directional WIMP search with LAr TPC. To validate this hypothesis\, we 
 conducted the Recoil Directionality (ReD) experiment to measure this corre
 lation in 70 keV nuclear recoils to the highest precision.\n\nThe ReD TPC 
 was carefully calibrated then irradiated with a neutron beam at the INFN L
 aboratori Nazionali del Sud\, Catania\, Italy. A model based on directiona
 l modulation in charge recombination was developed to explain the correlat
 ion. In this contribution\, we describe the experimental setup\, the theor
 etical model\, and the preliminary results from data analysis.\n\nhttps://

 \nWe are going to present the CYGNO project for the development of an high
  precision optical readout gaseous TPC for directional Dark Matter search 
 and solar neutrino spectroscopy\, to be hosted at Laboratori Nazionali del
  Gran Sasso. CYGNO (a CYGNus TPC with Optical readout) fits into the wider
  context of the CYGNUS proto-collaboration\, for the development of a Gala
 ctic Nuclear Recoil Observatory at the ton scale with directional sensitiv
 ity. CYGNO peculiar features are the use of sCMOS cameras and PMTs coupled
  to GEMs amplification of an Helium-based gas mixture at atmospheric press
 ure\, in order to achieve 3D tracking with head tail capability and backgr
 ound rejection down to few keV energy and boost sensitivity to low WIMP ma
 sses. We will discuss the latest R&D results within the CYGNO project and 
 the prospect for the upcoming underground installation of a 50 L prototype
  in Fall 2021\, soon to be followed by a O(1) m$^3$ experiment in 2023-202
 4. We will illustrate the synergy with the ERC Consolidator Grant project 
 INITIUM aimed at realising negative ion drift operation within the CYGNO 3
 D optical approach and how the reduced diffusion could boost the chosen ap

 nIn spite of the extensive search for the detection of the dark matter (DM
 )\, experiments have so far yielded null results: they are probing lower a
 nd lower cross-section values and are touching the so-called neutrino floo
 r. A way to possibly overcome the limitation of the neutrino floor is a di
 rectional sensitive approach: one of the most promising techniques for dir
 ectional detection is nuclear emulsion technology with nanometric resoluti
 on. The NEWSdm experiment\, located in the Gran Sasso underground laborato
 ry in Italy\, is based on novel nuclear emulsion acting both as the Weakly
  Interactive Massive Particle (WIMP) target and as the nanometric-accuracy
  tracking device. This would provide a powerful method of confirming the G
 alactic origin of the dark matter\, thanks to the cutting-edge technology 
 developed to readout sub-nanometric trajectories. In this talk we discuss 
 the experiment design\, its physics potential\, the performance achieved i
 n test beam measurements and the near-future plans. After the submission o
 f a Letter of Intent\, a new facility for emulsion handling was constructe
 d in the Gran Sasso underground laboratory which is now under commissionin
 g. A Conceptual Design Report is in preparation and will be submitted in S
 ummer 2021.\n\nhttps://indico.ific.uv.es/event/6178/contributions/15795/

DESCRIPTION:Speakers: Francesco Pandolfi (INFN Rome)\nWe present the lates
 t results on the development of the Dark-PMT\, a novel light Dark Matter (
 DM) detector. The detector is designed to be sensitive to DM particles wit
 h mass between 1 MeV and 1 GeV. The detection scheme is based on DM-electr
 on scattering inside a target made of vertically-aligned carbon nanotubes.
  Vertically-aligned carbon nanotubes have vanishing density in the directi
 on of the tube axes\, therefore the scattered electrons can leave the targ
 et without being reabsorbed only if their momentum is parallel to the tube
 s\, which is what happens when the tubes are parallel to the DM wind. This
  grants directional sensitivity to the detector\, a unique feature in this
  DM mass range. We will report on the construction of the first Dark-PMT p
 rototype\, on the establishment of a state-of-the-art carbon nanotube grow
 ing facility in Rome\, and on the characterizations of the nanotubes perfo
 rmed in Rome with XPS and angular-resolved UPS spectroscopy.\n\nhttps://in
