8. The EMC effect of light nuclei within the light-front Hamiltonian dynamics

Matteo Rinaldi (Istituto Nazionale di Fisica Nucleare)

11/10/2023, 14:00

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...

1. A global fit of unpolarised quark TMD PDFs at N3LL

Giuseppe Bozzi (University of Cagliari and INFN, Cagliari)

11/10/2023, 14:30

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 this talk I will present an extraction of unpolarized transverse-momentum-dependent parton distribution and fragmentation functions, based on more than two thousand data points from several experiments for two...

11. Heavy Barions and new Interacting Boson Fermion Fermion Model results

Hugo Garcia Tecocoatzi (Istituto Nazionale di Fisica Nucleare)

11/10/2023, 15:00

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...

14. Solving the homogeneus Bethe-Salpeter equation with a quantum annealer

Filippo Fornetti (Istituto Nazionale di Fisica Nucleare)

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...

48. The 3He spin-dependent structure functions within the Light-front Hamiltonian Dynamics

Eleonora Proietti (Istituto Nazionale di Fisica Nucleare)

11/10/2023, 15:40

In this talk I will present the results of the calculations of the spin-dependent structure functions (SSFs) of the 3He nucleus.
These quantities parametrize the hadronic tensor entering the deep inelastic scattering cross-section involving polarized beams and targets. In particular, the SSFs encode
relevant information on the spin structure of the target. In this analysis we calculate the...
