R4-3 Nuclei & Mesons (DNP) / Noyaux et mésons (DPN)
- Alexandros Gezerlis
In this talk I will provide motivation for determining the neutron radius of heavy nuclei, and why PREX II and CREX provide theoretically clean measurements in lead-208 and calcium-48. This will include a description of parity-violating electron scattering experimental design and efforts to minimize the systematic uncertainties. The neutron skin measurement on lead provides information about...
Hadronic structure is poorly understood as the properties of constituent quarks and gluons (e.g. spin, mass) do not explicitly add up to the properties of hadrons. The form factor describes the transverse position of partons inside a hadron. Perturbative QCD (pQCD) uniquely predicts the form factor at very high Q2, which is experimentally inaccessible. Different non-perturbative QCD models...
The $\eta$ meson offers the opportunity to probe a wide range of physics owing to its unique combination of additive quantum numbers, narrow mass width, and flavor-conserving decays. In particular, the $\eta$ meson provides a portal to look for beyond standard model (BSM) dark sector bosons, constraints to C-violating P-conserving physics, high precision tests of low-energy QCD descriptions,...
