Lepton-nucleus interaction is analyzed, in particular in the quasi-elastic region, using several nuclear models. The MEC are also included, that provide contributions in the so called 'dip region'. Both direct and exchange terms are evaluated.

The inverse process of ${}^{9}\mathrm{Be}$ photo-disintegration, including both sequential and direct reactions combining two $\alpha$ and a neutron into $^9\textrm{Be}$, is a reaction of astrophysical interest, because it represents an alternative path to the ${}^{12}\mathrm{C}$ formation in a neutron-rich environment. Here we present the study of the inclusive reaction $\gamma +...

We study dark matter scattering off ${}^2$H and ${}^4$He nuclei, assuming DM to be composed by weak interacting massive particles, WIMPs. In order to parametrize the WIMP-nucleon interaction the chiral effective field theory ($\chi$EFT) approach is used. Considering only interactions invariant under parity, charge conjugation and time reversal, we examine five interaction types: scalar,...

The necessity of calculating reliable nuclear matrix elements for neutrinoless double $\beta$ decay has further stimulated the research on the mechanisms responsible for the renormalization of the $\beta$-decay operator. We tackle this point using the many-body perturbation theory to derive effective Hamiltonian and operators for nuclear shell model calculations. Here, I will present recent...

In this talk I will discuss the calculation of the so called European Muon Collaboration (EMC) effect for light-nuclei. To this aim the nuclear structure is described within the relativistic Light-Front (LF) approach. Thanks to this choice, calculations fulfill Poincaré covariance, macroscopic locality, number of particles and momentum sum rules. The procedure has been applied to electron deep...

Building maps of the internal partonic structure of nucleons is a crucial step towards understanding the interactions between quarks and gluons and the phenomenon of confinement.

In the first part of the presentation, we present a study of the spectra and strong decay widths of heavy baryons. The masses of single heavy baryons up to the D-wave are calculated within a constituent quark model, employing both the three-quark and quark-diquark schemes. We calculated the decay widths of the ground and excited single heavy baryons into the heavy single...

This work aims to solve the Bethe-Salpeter equation (BSE) [1] of two massive scalars bound by the exchange of a massive scalar (solved in Ref. [2] with classical computation) with a Quantum Annealer (QA). One can transform the BSE into a non-symmetric generalized eigenvalue problem (GEVP) (see Ref. [2] for details). For our scope, we are interested to determine only in the maximum and minimum...

Gravitational wave events involving neutron stars provide interesting information of their interiors.

At the typical conditions of compact objects and related phenomena, exotic degrees of freedom such as free quarks are expected. The deconfinement of quarks in hadronic matter begins after the first seed of quark matter is created. This process is called nucleation, which occurs by local thermal or quantum fluctuations when the hadronic phase is metastable. I will initially present the...

Studies of neutrinos from astrophysical environments such as core-collapse supernovae, neutron star mergers and the early universe provide a large amount of information about various phenomena occurring in them. The description of the flavor oscillation is a crucial aspect for such studies, since the physics of matter under extreme conditions is strongly flavor-dependents. The neutrino flavor...

20. Systematics of reaction cross sections from double folding and single folding optical potentialsImane Moumene (University of Milano)10/12/23, 11:45 AM
The study of knockout reactions in which exotic nuclei are used as projectiles, is a hot research topic. We evaluate the accuracy of the description of the core-target interaction, by comparing theoretical and experimental reaction cross sections for a large dataset of knockout reactions carried out with light projectiles on a 9Be target. Our results show that single-folded potential,...

The formation of nuclear clusters constitutes an essential feature for the construction of global and unified equation-of-state (EoS) for nuclear matter. They emerge as many-body correlations, which can be attributed to the nucleon-nucleon (NN) interaction, and exist at sub-saturation densities in nuclear matter.
Phenomenological models that make use of energy density functionals (EDFs)...

We develop a kinetic approach to the production of light nuclei up to mass number A = 4 in intermediate-energy heavy-ion collisions by including them as dynamic degrees of freedom. The conversions between nucleons and light nuclei during the collisions are incorporated dynamically via the breakup of light nuclei by a nucleon and their inverse reactions. We also include the Mott effect on light...

We discuss the diffusion and the energy loss of heavy quarks (HQs), charm and beauty, in relativistic heavy ion collisions. HQs are produced by hard QCD scatterings in the very early stage of the collision. Consequently, they probe the entire evolution of the medium produced by the collision, from the pre-equilibrium stage up to the freezout passing by the evolution in the quark-gluon plasma...

In the description of the heavy-ion collisions, the success of hydrodynamics even when the system is far from equilibrium has raised some questions about the applicability of this theory and about the evolution of the medium itself, especially for smaller systems like p-A and p-p collisions. It has been found that, well before equilibrium is reached, systems with different initial conditions...

Open quantum systems (OQS) have shown a good performance within other fields of physics, including quantum optics and solid state physics. Recently, it has been implemented in the Heavy Ion Collisions (HIC) field to study different kinds of events such as jet quenching or quarkonia propagation inside the quark-gluon plasma. We will do an overview of OQS towards the motivation and its...

The initial stage of Ultra Relativistic Heavy Ion Collisions is dominated by low Bjorken-x degrees of freedom, which can be understood as a classical color field, obeying classical Yang-Mills equations. Such a phase, occurring in the first fractions of a fm after the collision and leading towards an equilibrated quark gluon plasma, is called the Glasma. Indeed, we will discuss particle...

At the turn of the century, the availability of larger and more powerful supercomputers made it possible to push the lattice QCD calculations down into the deep infrared, where ordinary perturbation theory fails due to the presence of a Landau pole in its running coupling constant. There it was discovered that, instead of growing to infinity as would be typical of a massless field, the gluon...

We compute ground-state properties of atomic nuclei with up to A = 20 nucleons, using as input a leading order pionless effective field theory Hamiltonian. A variational Monte Carlo method based on a new, highly-expressive, neural-network quantum state ansatz is employed to solve the many-body Schroedinger equation in a systematically improvable fashion. In addition to binding energies and...

In noncentral relativistic heavy-ion collisions, the system carries a large initial orbital angular momentum, inducing strong vorticity fields and magnetic fields in the quark-gluon plasma. These fields will in turn polarize partons and are converted into spin polarization for baryons and spin alignment for vector mesons at the hadronization stage. Based on the Kadanoff-Baym equations on the...
