Nowadays, the search for neutrino-less double beta (0$\nu\beta\beta$) decay continues with undiminished interest since it is a prominent tool for probing the absolute neutrino mass scale. However, this task is hampered by our limited knowledge of the nuclear matrix elements (NMEs) for such an exotic process. In this respect, a seminal experimental campaign has been initiated at the Istituto...
The nature of the neutrinoless double-beta decay remains one of the most talked topics in nuclear and particle physics. Observing this kind of decay would shed light on the nature of the neutrino, including its mass. Our goal is to calculate the phase space factors and nuclear matrix elements concerning the decay of $^{104}$Ru. The phase space factors are evaluated using exact Dirac electron...
PROSPECT is a reactor antineutrino experiment consisting of a 4-ton liquid scintillator antineutrino detector divided into an 11x14 array of optically separated segments. The detector was designed to probe the existence of sterile neutrino oscillations and precisely measure the antineutrino spectrum resulting from 235U fission. Data was taken in 2018 and 2019 with a first-generation detector...
The Recoil Directionality project (ReD) within the Global Argon Dark Matter Collaboration aims to characterize the response of a liquid argon (LAr) dual-phase Time Projection Chamber (TPC) to neutron-induced nuclear recoils and to measure the charge yield for low-energy recoils. The charge yield is a critical parameter for the experiments searching for dark matter in the form of low-mass WIMPs...
We explore the possibility of using the recently proposed THEIA detector to measure the $\bar \nu_\mu \rightarrow \bar \nu_e$ oscillation with neutrinos from a muon decay at rest ($\mu$DAR) source to improve the leptonic CP phase measurement. Due to its intrinsic low-energy beam, this $\mu$THEIA configuration ($\mu$DAR neutrinos at THEIA) is only sensitive to the genuine leptonic CP phase...
The NUMEN project [1-2] aims to investigate specific heavy–ion double charge exchange (DCE) reactions in order to provide experimentally driven information about nuclear matrix elements (ΝΜΕs) of interest in the context of neutrinoless double beta decay (0$\nu\beta\beta$). To this extent, the $^{20}$Ne + $^{130}$Te system was experimentally investigated in a multi-channel approach by measuring...
We study the one-nucleon transfer in heavy-ion-induced reactions. We investigate the transitions between even-even and odd-even nuclei. The even-even nuclei are candidates to decay via double beta emission without neutrinos. This subject is relevant for current and future experiments at LNS as part of the NUMEN project.

The NUMEN experiment, hosted at LNS (Catania, Italy), aims to determine the Nuclear Matrix Elements (NMEs) involved in 0νββ decay via heavy-ion induced Double Charge...
Symmetries of the IBFFM will be discussed and Spectroscopic Amplitudes
(SA) in the Interacting Boson Fermion Fermion Model (IBFFM) are
necessary for the computation of 0\nu\beta\beta0νββ decays but also for
cross-sections of heavy-ion reactions, in particular, Double Charge
Exchange reactions for the NUMEN collaboration, if one does not want to
use the closure limit. We present for the...
JUNO (Jiangmen Underground Neutrino Observatory) is a neutrino experiment under construction in China. It will be the largest liquid scintillator experiment, detecting neutrinos and anti-neutrinos by using 20 kton of organic liquid scintillator contained in an huge Acrylic vessel of 35 m diameter. The experiment will start the data-taking in 2024 with the main goal to determine the Neutrino...
Using the Glashow resonance candidate event recently identified by IceCube we infer the ultrahigh energy astrophysical neutrino source. The Glashow resonance is a valuable probe to identify the source of astrophysical neutrinos because it distinguishes $\bar{\nu_e}$ from $\nu_e$. With the available experimental information we set a constraint on the $\bar{\nu_e}$ fraction of astrophysical...
Heavy ion double charge exchange (HIDCE) nuclear reactions represent an alternative tool to gain information on the Nuclear Matrix Elements (NMEs) of double beta decay processes. This talk focuses on the formalism developed for describing HIDCE nuclear reactions in terms of sequential
meson-exchange, i.e. as a sequence of two Single Charge Exchange transitions (DSCE). The DSCE cross section...
