Large liquid argon (LAr) volumes are integral to modern particle and nuclear physics experiments, specifically for detecting weakly interacting particles such as neutrinos and dark matter. Ensuring detector performance and optimal detection efficiency requires comprehensive LAr characterization and efficient monitoring of recirculation systems. High-resolution temperature monitoring systems,...
The Deep Underground Neutrino Experiment (DUNE) is a 1300 km baseline neutrino experiment able to resolve the neutrino mass hierarchy and CP-violation. The Far Detector (FD) consists of four liquid argon TPC (10 kton fiducial mass) with systems for the detection of charge and scintillation light produced by an ionization event. Before their installation in the FD, this technology is being...
SBND is a Liquid Argon Time Projection Chamber (LArTPC), serving as the near detector of the Short Baseline Neutrino program at Fermilab. Its near location (110 m) to the neutrino source and relatively large mass (112 ton active volume) will allow studying neutrino interactions on argon with unprecedented precision. The detector is currently finishing the commissioning phase and has collected...
Detection of the vacuum ultraviolet (VUV) scintillation light produced by liquid noble elements will be of central importance to fully exploit the potential of future time projection chambers (TPCs) using these media. A novel technology recently proposed to detect VUV light is based on a windowless amorphous selenium photosensor. This device would open the door to the possibility of making an...
The LiquidO collaboration proposes a new method for detecting particles using opaque scintillator, which breaks the traditional paradigm of transparency. LiquidO technology exploits the stochastic confinement of the scintillation photons within a few cm radius near its creation point due to the short scattering length and the collection of the trapped light through arrays of...
The NEXT-100 detector will search for neutrinoless double beta decay in 136Xe and is currently operating at the Laboratorio Subterráneo de Canfranc (LSC). The NEXT (Neutrino Experiment with a Xenon TPC) program employs electroluminescent TPCs (time projection chambers) to detect and track energetic electrons with good energy resolution. NEXT has operated several prototypes to demonstrate the...
Using an effective field theory approach, we study coherent neutrino scattering on nuclei, in the setup pertinent to the COHERENT experiment. We include non-standard effects in both neutrino production and detection, with an arbitrary flavor structure and all leading Wilson coefficients simultaneously present. The tree main tools of this work are a QFT description of neutrino interactions1, a...
The ANAIS experiment aims to independently verify or refute the
longstanding positive annual modulation signal observed by DAMA/LIBRA
using the same target and technique. While other experiments have ruled
out the parameter region highlighted by DAMA/LIBRA, their results rely
on assumptions on the dark matter particle and its velocity
distribution, as they utilize different target materials....
DarkSide-20k is under construction at LNGS and is designed to lead the search for heavy WIMPs in the coming years. Argon has the advantage of pulse shape discrimination compared to other noble elements, but has the drawback of the cosmogenically induced Ar-39 content with an activity of 0.96 Bq/kg. Getting rid of this background is pivotal for the success of our scientific program. Hence, the...
DEAP-3600 is a single-phase liquid argon (LAr) direct-detection dark matter experiment, operating 2 km underground at SNOLAB (Sudbury, Canada). The detector consists of 3.3 tons of Lar contained in a spherical acrylic vessel. At WIMP masses of 100 GeV, DEAP-3600 has a projected sensitivity of 10−46 cm2 for the spin independent elastic scattering cross section of WIMPs. External radioactive...
Dark matter direct detection is now standing at an interesting point where the neutrino background and the upper bound on the dark matter signal cross section are starting to overlap in a region of dark matter mass of around 10 GeV. However, if there exists BSM physics with isospin violating interactions between the dark and the SM sectors, both the neutrino fog and the DM exclusion bounds are...
A range of haloscope searches are currently probing axions in the mass range ~2-40 micro-eV. However, simulations of the axion field in the early Universe are increasingly pointing towards heavier masses if we want the axion to comprise all of the Dark Matter in the Universe. I will present the Canfranc Axion Detection Experiment (CADEx), a proposed haloscope search in the well-motivated but...
The Canfranc Axion Detection Experiment (CADEx) will search for the axion in the yet unexplored mass range of 330-460 micro-electronvolts (µeV). Operating in the W-band (75-100 GHz), CADEx will be installed in a dilution cryostat at the Canfranc Underground Laboratory (LSC), combining, for the first time, a cavity haloscope in a strong magnetic field with a camera made with Kinetic Inductance...
The quest for feebly or weakly interacting particles (FIPs) arising in low-scale New Physics (NP) scenarios is a very active topic. NA64 is a world-reference fixed target experiment at CERN searching for FIPs in the scattering of electron, positron and muons on a target. Several and well-motivated NP scenarios suggest FIPs particles preferably coupled to muons as: Z' bosons in...
Axion-like particles (ALPs) can be copiously produced in core-collapse supernovae (SN) due to their coupling to SN matter. If they are weakly coupled, ALPs leave the star unimpeded after being produced. This regime has already been tightly constrained by cooling bounds. In this talk, I will focus on the trapping regime, where the SN environment becomes optically thick for ALPs and, therefore,...
The persistent discrepancy in the Hubble constant determinations, known as the Hubble tension, represents one of the most intriguing challenges in modern cosmology. For this reason, results from new and independent techniques are especially compelling. We will present the latest estimates on the Hubble constant (H0) from gamma-ray attenuation that uses optical depths calculations from a recent...
Very-high-energy (VHE) gamma-ray astroparticle physics is a relatively young field. Observations over the past decades have revealed about 250 VHE emitters that appear to act as cosmic particle accelerators, boosting the field significantly. These findings prove that the detection technique based on imaging atmospheric Cherenkov telescopes (IACT) has reached a level of maturity that allows the...
Cosmic rays, discovered in 1912, were initially crucial for uncovering new fundamental particles and have since become key to understanding broader astrophysical phenomena. Today, they provide essential data for multi-messenger astronomy and serve as tools for probing near-Earth space and solar activity. To enhance our understanding of cosmic rays, a new family of modular detectors, called...
The measurement of the various cosmic-ray fluxes of nuclei are paramount for the understanding of the propagation in the galaxy and the determination of relevant physical quantities like the diffusion coefficient and the halo size. Due to its large acceptance and long mission onboard the International Space Station, AMS has performed precise measurements of 16 fluxes of nuclei in cosmic rays...
The Alpha Magnetic Spectrometer (AMS) is a multipurpose particle detector operating on the International Space Station since May 2011. After 13 years, AMS has measured more than 240 billion cosmic rays with unprecedented precision. The measurements of positron and electron fluxes have shown unforeseen spectral features that cannot be explained with the traditional models of galactic cosmic...
The KM3NeT collaboration is building a multi-site neutrino telescope in the Mediterranean Sea, with two detectors currently in partial deployment. One detector is ORCA, in front of the French coast of Toulon, sensitive to energies ranging from GeV to few TeV and with the study of neutrino properties as the main scientific goal. The other detector, ARCA, next to Sicily in Italy, is sensitive to...
In recent years, the development of multi-messenger astronomy has opened a new window into understanding the most energetic phenomena of our Universe. The study of transient events by combining information from neutrinos, photons, charged particles, and gravitational waves enhances the sensitivity to identifying and characterising a wide variety of astrophysical sources.
The KM3NeT neutrino...
