Valence-quark distributions of pions and kaons in a nuclear medium
Combining the Nambu-Jona-Lasinio and quark-meson coupling models predicts that nuclear matter barely changes pion valence quark distributions while kaon valence u and anti-s distributions shift in opposite x-regions at higher density.
