关于广义形状因子的QCD演化的一个注记

A note on the QCD evolution of generalized form factors

Wojciech Broniowski, Enrique Ruiz Arriola

摘要:

强子的广义形状因子是出现在广义部分子分布矩中的对象。它们的首阶DGLAP-ERBL QCD演化非常简单,其解是以线性方程组的矩阵三角结构给出的,其中系数是演化比。我们指出,这种解决方案在分析中具有实际的重要性,其中广义形状因子是基本对象,例如,格规研究或模型。它还显示了它们演变的一般特征。

英文摘要:

Generalized form factors of hadrons are objects appearing in moments of the generalized parton distributions. Their leading-order DGLAP-ERBL QCD evolution is exceedingly simple and the solution is given in terms of matrix triangular structures of linear equations where the coefficients are the evolution ratios. We point out that this solution has a practical importance in analyses where the generalized form factors are basic objects, e.g., the lattice-gauge studies or models. It also displays general features of their evolution.
