Pions in isospin asymmetric nuclei
arXiv:nucl-th/0103042 · doi:10.1016/S0370-2693(01)00947-9
Abstract
Using a pair of the lightest mirror nuclei, He and H, we study the effect of the medium modification of pion fields on the flavor non-singlet structure function. The change of the pion fields leads to an enhancement of the flavor asymmetry of the antiquark distributions in a nucleus.
