Nuclear Physics
Our understanding of the origin of heavy elements by the r-process has made great progress in the last years. In addition to the gravitational wave and kilonova observations for GW170817, there have been major advances in the hydrodynamical simulations of neutron star mergers and core-collapse supernovae, in the microphysics included in those simulations (neutrinos and high density equation of...
Nuclear forces that govern the atomic nuclei are still not fully understood. The state-of-the-art nuclear theories are dealing with the complexity of the nuclear systems governed by many
degrees of freedom. In order to shed light to these advance models, nuclear spectroscopy has been proven to be of outmost importance to obtained experimental information of key nuclear observables.
From the...
The description of the proton properties from its quark and gluon substructure is a topic which is far from being well understood. The strong force binding together the constituents behaves remarkably differently at high and low energies.
The main experimental tool to probe the proton is electron scattering off proton targets. At high energies, the electrons break up the protons and the...
SCK CEN is at the forefront of Heavy Liquid Metal (HLM) nuclear technology worldwide with the development of the MYRRHA accelerator driven system (ADS) since 1998.
MYRRHA is conceived as a flexible fast-spectrum research irradiation facility cooled by Lead Bismuth Eutectic (LBE). The nominal design power of the MYRRHA reactor is 70 MWth. It is driven in sub-critical mode by a high power...
The interplay between the experimental results generated in terrestrial laboratories and the observations coming from stellar objects is of fundamental importance for offering solutions to long-standing puzzles in the physics of strongly interacting matter under extreme conditions. In this talk I will present the work I have been developing over the years regarding dense matter at finite...
We analize the role played by the thermal f0(500) state or σ in chiral symmetry restoration and propose an alternative sector (related with the thermal K∗0(700) or κ) to study O(4)×UA(1) restoration. The temperature corrections to the spectral properties of those states are included in order to provide a better description of the scalar susceptibilities χS and χκS around the transition region....
We study the dependence of hadronic resonances on the mass of quarks through the analysis of data from QCD lattice simulations form various collaborations. Using Machine Learning techniques as the LASSO algorithm we fit lattice data in order to extrapolate them to the physical point and extract the results for the quark mass dependence for exotic resonances like Ds0 and Ds1.
Observing neutrinoless double-beta (0νββ) is undoubtedly one of the most anticipated breakthroughs in modern-day neutrino, nuclear and particle physics. When observed, the lepton-number-violating process would provide unique vistas beyond the Standard model of particle physics. However, the expected decay rates depend on coupling constants, whose effective values are under debate, and nuclear...
Neutrinoless double-beta (0νββ) decay is a hypothetical nuclear process where two neutrons transmute into two protons, with only two electrons being emitted with no accompanying antineutrinos. The measurement of such a process would imply that neutrinos are Majorana particles (their own antiparticle) and, since lepton number would not be conserved, this would point to an event beyond the...
Nucleosynthesis is an ongoing process in the cosmos which take place in various astrophysical environments such as massive stars, core-collapse supernovae or novae. One of the most famous example of evidence in the continuity of the process was the discovery of γ-ray from radioactive 26Al in 1982 [1]. More recently, an all-sky map of this characteristic 1809-keV γ-ray shows a distribution of...
Study of heavy-ion interactions using α and non-α structure beams at low energies [1-4] may provide a great deal of information on the in-complete fusion (ICF) reactions. In order to understand the dynamics of ICF reactions, several studies have been made and a large enhancement in cross section for α-emitting channels with respect to the calculations done with code PACE4[5] has been reported...
In stellar evolution, the rate of 12C(α,γ)16O reaction controls the C/O abundance ratio at the end of the helium burning phase, thus defining the further course of development. At stellar temperatures of around 300 keV, the cross section of 12C(α,γ)16O is ∼ 10−17 b, which cannot be measured using current technology. The α−capture reaction populating the natural-parity states of the residual...
The pairing interaction induces nucleon-nucleon correlations that are essential in defining the properties of finite quantum many-body systems close to their ground states. A very specific probe of this pairing component in the nuclear interactions, which ties up nucleons in a highly correlated state, the nuclear Cooper pairs, is the two-nucleon transfer reactions. How paring correlations can...
Nuclear equation of state (EOS) describes the relationship between state variables such as density, pressure and temperature of a nuclear system. It is usually expressed as the energy per nucleon of a particular nuclear medium. Constraining parameters of nuclear EOS of asymmetric nuclear matter (where asymmetry lies in proton to neutron number) is of immense importance for understanding not...
The tin (Sn; Z = 50) isotopes constitute the longest chain of semi-magic even-even nuclei between the 100Sn (N = 50) and 132Sn (N = 82) double-shell closures, seven of which, 112,114,116,118,120,122,124Sn, are stable. These isotopes have become a prototypical benchmark of extensive microscopic theory and experiment, reflected in the large number of studies investigating the decay of their...
Collinear laser spectroscopy provides access to many nuclear properties such as isotopic shifts of the nuclear mean square charge radii, spins, nuclear magnetic moments and electric quadrupole moments. As measurements are carried out on a small time scale, this method is well suited for the investigation of isotopes far from stability.
The development of many different techniques used in...

In this work, we carry out a suite of specially-designed numerical simulations to shed further light on dark matter (DM) subhalo survival at mass scales relevant for gamma-ray DM searches, a topic subject to intense debate nowadays. Specifically, we have developed and employed an improved version of DASH, a GPU N-body code, to study the evolution of low-mass subhaloes inside a Milky Way-like...
