非定域凝聚与π介子形状因子

Nonlocal condensates and pion form factor

A. V. Pimikov, A. P. Bakulev, N. G. Stefanis

摘要:

本文综述了非定域凝聚方法及其在类空电磁π介子形状因子的QCD求和规则中的应用。结果表明,凝聚体的非定域性是一个关键点,包括非微扰贡献的π形状因子。

英文摘要:

We review a nonlocal-condensate approach and its application in QCD sum rules for the spacelike electromagnetic pion form factor. It is shown that the nonlocality of the condensates is a key point to include nonperturbative contributions to the pion form factor.
