论文摘要
我们介绍了Quark-Gluon顶点的纵向$和$横向形式的初步结果,作为传入和即将上流夸克Momenta的函数以及它们之间的角度$θ=2π/3 $。这些形式因素的表达式先前是从斯拉夫诺夫·泰勒的身份,量规协方差和乘法性重差划分的限制来限制了费米昂 - 波森顶点的。
We present preliminary results on the longitudinal $and$ transverse form factors of the quark-gluon vertex as functions of the incoming and outgoing quark momenta and an angle $θ=2π/3$ between them. The expressions for these form factors were previously derived from Slavnov-Taylor identities, gauge covariance and multiplicative renormalizability that firmly constrain the fermion-boson vertex.
