Lipatov有效action形式体系中双胶子的产生

Production of two gluons in the Lipatov effective action formalism

M. A. Braun, M. Yu. Salykin, M. I. Vyazovsky

摘要:

在Lipatov有效作用量理论下,研究了两个具有不同快度的实胶子辐射的单圈衍射振幅。结果表明,积分后的纵向动量的循环所得到的表达式与Lipatov-Bartels形式主义在横向空间提供了相同的处方是用来排除发散的贡献,如以前提出的一个单一的实胶子的发射得到的一致。

英文摘要:

The one-loop diffractive amplitude for emission of two real gluons with widely different rapidities is studied in the Lipatov effective action formalism. It is shown that after integration over longitudinal momenta in the loop the resulting expression coincides with the one obtained by the Lipatov-Bartels formalism in transversal space provided the same prescription is used to exclude divergent contributions as previously proposed for emission of a single real gluon.
