摘要

我们利用光锥夸克模型，计算了零温等时空不对称核物质中最轻伪谱介子--小离子--的价夸克横动量相关部分子分布（TMDs）。利用手性苏(3)夸克均场模型计算的有效夸克质量诱导了先锋非极化 TMD 的介质修正。我们还计算了不同重子密度下不同动量分数（x）的自旋密度。

Does nuclear medium affect the transverse momentum-dependent parton distributions of valence quark of pions?

We calculate the valence quark transverse momentum-dependent parton distributions (TMDs) of the lightest pseudoscalar meson, pions, in isospin asymmetric nuclear matter at zero temperature by employing a light-cone quark model. The medium modifications in the pion unpolarized TMDs are induced through the effective quark masses computed using the chiral SU(3) quark mean field model. The spin densities at different momentum fraction (x) have also been calculated at different baryonic densities.
