In-Medium Pion Valence Distributions in a Light-Front Model
arXiv:1608.03858 · doi:10.1016/j.physletb.2017.01.004
Abstract
Pion valence distributions in nuclear medium and vacuum are studied in a light-front constituent quark model. The in-medium input for studying the pion properties is calculated by the quark-meson coupling model. We find that the in-medium pion valence distribution, as well as the in-medium pion valence wave function, are substantially modified at normal nuclear matter density, due to the reduction in the pion decay constant.
