本研究结合CQMF模型与光锥夸克模型,系统分析有限温度磁化核介质中磁场、密度、温度及同位旋不对称性对π介子部分子分布函数和电磁形状因子的影响,揭示介质对π介子内部结构的显著调制作用。

AI 中文摘要

我们通过分析π介子部分子分布函数(PDFs)和电磁形状因子(EMFFs)的介质内修正,研究了有限温度下磁化核介质中π介子的结构。我们采用了一个统一框架,结合手征SU(3)夸克平均场(CQMF)模型和光锥夸克模型(LCQM),其中介质内夸克质量使用CQMF模型计算,随后作为输入用于光锥形式体系。该研究系统地探讨了磁场、重子密度、温度和同位旋不对称性对π介子结构的影响。此外,还纳入了狄拉克海贡献以考虑介质中的真空极化效应。我们的PDFs和EMFFs结果为极端条件下π介子性质的修正提供了有价值的见解,强调了周围介质在改变其内部结构中的重要作用。

英文摘要

We investigate the structure of the pion in a magnetized nuclear medium at finite temperature by analyzing the in-medium modifications of its parton distribution functions (PDFs) and electromagnetic form factors (EMFFs). We use a unified framework combining the chiral SU(3) quark mean field (CQMF) model and the light-cone quark model (LCQM) where the in-medium quark masses are evaluated using the CQMF model and subsequently employed as inputs in the light-cone formalism. The study systematically explores the effects of magnetic field, baryon density, temperature, and isospin asymmetry on the pion structure. In addition, Dirac sea contributions are incorporated to account for vacuum polarization effects in the medium. Our results of PDFs and EMFFs provide valuable insights into the modification of pion properties under extreme conditions, highlighting the significant role of the surrounding medium in altering its internal structure.
