Constraining nucleon high momentum in nuclei
Gao-Chan Yong🇨🇳
Recent studies at Jefferson Lab show that there are a certain proportion of nucleons in nuclei have momenta greater than the so-called nuclear Fermi momentum $p_{F}$ . Based on the transport model of nucleus-nucleus collisions at intermediate energies, nucleon high momentum caused by the neutron-proton short-range correlations in nuclei is constrained by comparing with $π$ and photon experimental data and considering some uncertainties. The high momentum cutoff value $p_{ma x}$ $\leq$ 2 $p_{F}$ is obtained.

Core-collapse supernova matter: light clusters, pasta phase and phase transitions
Helena Pais🇵🇹 · Constança Providência🇵🇹 · William G. Newton🇺🇸 · Jirina R. Stone🇬🇧
The pasta phase in core-collapse supernova matter (finite temperatures and fixed proton fractions) is studied within relativistic mean field models. Two different calculations are used for comparison, the Thomas-Fermi (TF) and the Coexisting Phases (CP) approximations. The effects of including light clusters in nuclear matter and the densities at which the transitions between pasta configurations and to uniform matter occur are also investigated. Finally, a comparison with a finite temperature Skyrme-Hartree-Fock calculation is drawn.
