全息QCD中的横向电荷密度和磁化强度

Transverse charge and magnetization densities in holographic QCD

Dipankar Chakrabarti, Chandan Mondal

摘要:

本文研究了非极化和横向极化核子的横向电荷和反常磁化强度密度的味结构。我们考虑了全息QCD中电磁形状因子的两种不同模型。味形状因子是利用电荷和同位旋对称性对核子的Dirac和Pauli形状因子进行分解得到的。两个标准的唯象参数化的结果进行了比较。

英文摘要:

We present a study of flavor structures of transverse charge and anomalous magnetization densities for both unpolarized and transversely polarized nucleons. We consider two different models for the electromagnetic form factors in holographic QCD. The flavor form factors are obtained by decomposing the Dirac and Pauli form factors for nucleons using the charge and isospin symmetry. The results are compared with two standard phenomenological parametrizations.
