چکیده

Recent precise parity-violating electron scattering experiments on $^{48}$Ca (CREX) and $^{208}$Pb (PREX-II) provide a new insight the formation of neutron skin in nuclei. Within energy density functional (EDF) framework, we investigate implications CREX PREX-II data nuclear matter symmetry isovector properties finite nuclei: thickness dipole polarizability. The weak-charge form factors from are employed directly constraining relativistic density-dependent point coupling EDFs. EDF established with acquires considerably smaller values parameters, polarizability both for $^{208}$Pb, comparison to obtained using data, previously Presented analysis shows that could not consistent constraints sector EDFs, further theoretical experimental studies required.

Parity-Violating Electron Scattering

Measurements of parity-violating asymmetries in the scattering of longitudinally polarized electrons off unpolarized fixed targets are used to access leptonic and semi-leptonic weak neutral current amplitudes. One thrust of the current program is the measurement the elastic neutral weak amplitude at very low Q from scattering off a heavy spinless nucleus, which is sensitive to the presence of a...

The deuteron and pn scattering-state wave functions are obtained from solutions of a Schrödinger equation with the Argonne v18 potential. Electromagnetic and weak neutral oneand two-nucleon currents are included in th...

Parity-violating Electron Scattering and Nucleon Structure

The measurement of parity violation in the helicity dependence of electronnucleon scattering provides unique information about the basic quark structure of the nucleons. In this review, the general formalism of parity-violating electron scattering is presented, with emphasis on elastic electron-nucleon scattering. The physics issues addressed by such experiments is discussed, and the major goal...

Probing supersymmetry with parity-violating electron scattering

We compute the one-loop supersymmetric ~SUSY! contributions to the weak charges of the electron (QW e ), proton (QW p ), and cesium nucleus (QW ) in the minimal supersymmetric standard model ~MSSM!. Such contributions can generate several percent corrections to the corresponding standard model values. The magnitudes of the SUSY loop corrections to QW e and QW p are correlated over nearly all of...
