标题： Valence quark properties of charged kaons in symmetric nuclear matter

摘要： 我们通过使用光锥夸克模型，在零温下计算了同位旋对称核物质中带电介子的领先阶价夸克横向动量分布函数(TMDs)和广义部分子分布(GPDs)。 通过采用手征SU($3$)夸克平均场模型的输入，已经完成了非极化TMDs和GPDs的介质修正。 电磁形式因子(EMFFs)和电荷半径已从非极化的GPDs中计算出来，适用于真空和介质情况。 我们还计算了高重子密度下活性夸克的平均横向和纵向动量的变化。 这些结果与可用的实验数据以及其他模型预测结果非常一致。 显示英文摘要

摘要： We calculate the leading twist valence quark transverse momentum parton distribution functions (TMDs) and generalized parton distributions (GPDs) of the charged kaons in an isospin symmetric nuclear matter at zero temperature by employing the light-cone quark model. The medium modifications of the unpolarized TMDs and GPDs have been carried out by taking inputs from the chiral SU($3$) quark mean field model. The electromagnetic form factors (EMFFs) and charge radii have been calculated from the unpolarized GPDs for both the vacuum and in-medium cases. We have also calculated the variation of average transverse and longitudinal momenta for the active quark at high baryonic density. These results are found to be in good agreement with the available experimental data as well as with other model predictions.
