高阶胶子饱和与运动学的改进

Gluon saturation at higher orders and improvement of kinematics

Guillaume Beuf

摘要:

标准的微扰计算导致病态大的非线性光学校正低$x_{Bj}$演化方程,如BFKL和BK。使用更精细的治疗运动学在混合空间,相关时胶子饱和集,得到一个改进版本的BK方程,所有订单的最严重的那些大的高阶修正。

英文摘要:

Standard perturbative calculations lead to pathologically large NLO corrections to low-$x_{Bj}$ evolution equations like BFKL and BK. Using a more refined treatment of kinematics in mixed-space, relevant when gluon saturation sets on, one obtains an improved version of the BK equation, resumming to all orders the most severe of those large higher order corrections.
