手征微扰理论中核子广义部分子分布的一阶矩

First moments of nucleon generalized parton distributions in chiral perturbation theory at full one-loop order

Philipp Wein, Peter C. Bruns, Andreas Schäfer

摘要:

本文给出了与手征偶广义部分子分布一阶矩有关的广义形状因子的手征外推公式。对于低能QCD的描述,我们采用了双味协变重子手征微扰理论的框架。我们的结果非常适合于将格点量子色动力学数据外推到物理夸克质量。

英文摘要:

In this paper we present chiral extrapolation formulas for the generalized form factors connected to the first moments of chiral-even generalized parton distributions. For the description of QCD at low energies we employ the framework of two-flavor covariant baryon chiral perturbation theory at full one-loop accuracy. Our results are well suited for the extrapolation of lattice QCD data to physical quark masses.
