虚光子结构函数中的重夸克效应

Heavy Quark Effects in the Virtual Photon Structure Functions

Yoshio Kitadono, Ken Sasaki, Takahiro Ueda, Tsuneo Uematsu

摘要:

在质量无关的重整化群方程(RGE)框架下研究了虚光子结构函数$F_{2}^γ(x, Q^2, P^2)$和$F_{L}^γ(x, Q^2, P^2)$中的重夸克质量效应.本文研究了一种基于部分子图像和算子乘积展开(OPE)处理重夸克质量效应的形式,并对QCD中的$F_{\rm eff}^γ(x, Q^2, P^2)$进行了数值计算.

英文摘要:

We investigate the heavy quark mass effects in the virtual photon structure functions $F_{2}^γ(x, Q^2, P^2)$ and $F_{L}^γ(x, Q^2, P^2)$ in the framework of the mass-independent renormalization group equation (RGE). We study a formalism in which the heavy quark mass effects are treated based on parton picture as well as on the operator product expansion (OPE), and perform the numerical evaluation of $F_{\rm eff}^γ(x, Q^2, P^2)$ to the next-leading order (NLO) in QCD.
