Constraining nucleon high momentum in nuclei

Abstract

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 $\pi$ and photon experimental data and considering some uncertainties. The high momentum cutoff value $p_{max}$ $\le$ 2$p_F$ is obtained.
