基于k_T分解的NLO喷气生产

NLO jet production in k_T factorization

J. Bartels, A. Sabio Vera, F. Schwennsen

摘要:

本文在次领先阶kT分解(next-to-leading order,NLO)的背景下讨论了中心快度区喷流的包容产生。利用NLO BFKL结果在Regge限值中进行计算。我们引入了喷流锥的定义,并进行了适当的相空间分离到多Regge和准多Regge运动区域。我们讨论两种情况:高度虚光子的散射,这需要一个对称的能量尺度来分离胶子格林函数的影响因子,以及强子-强子碰撞,其中需要一个非对称的尺度选择。

英文摘要:

We discuss the inclusive production of jets in the central region of rapidity in the context of k_T-factorization at next-to-leading order (NLO). Calculations are performed in the Regge limit making use of the NLO BFKL results. We introduce a jet cone definition and carry out a proper phase--space separation into multi-Regge and quasi-multi-Regge kinematic regions. We discuss two situations: scattering of highly virtual photons, which requires a symmetric energy scale to separate impact factors from the gluon Green's function, and hadron-hadron collisions, where a non-symmetric scale choice is needed.
