First-principles results for electromagnetic properties of $sd$ shell nuclei

, 2017
In this work we present $ab~initio$ shell-model calculations for electric quadrupole moments and magnetic dipole moments of $sd$ shell nuclei using valence-space Hamiltonians derived with two $ab~initio$ approaches: the in-medium similarity ...

Combined parametrization of the neutron electric form factor and the $\gamma^\ast N \to \Delta(1232)$ quadrupole form factors

, 2019
Models based on $SU(6)$ symmetry breaking and large $N_c$ limit provide relations between the pion cloud contributions to the $\gamma^\ast N \to \Delta(1232)$ quadrupole form factors, electric ($G_E$) and Coulomb ($G_C$), and the neutron electric form ...

Delta electromagnetic form factors and quark transverse charge densities from lattice QCD

, 2009
We discuss the techniques to extract the electromagnetic Delta form factors in Lattice QCD. We evaluate these form factors using dynamical fermions with smallest pion mass of about 350 MeV.
