Electroweak Sudakov Corrections using Effective Field Theory

Jui-yu Chiu, Frank Golf, Randall Kelley, Aneesh V. Manohar

摘要:

用软共线有效理论(SCET)中的重整化群演化方法对形式为α ^n log^m s/ M_{W,Z} ^2的电弱Sudakov修正求和。给出了费米子和标量粒子的标量、矢量和张量形状因子的结果。发展了SCET中包含质量规范玻色子的形式。

英文摘要:

Electroweak Sudakov corrections of the form alpha^n log^m s/M_{W,Z}^2 are summed using renormalization group evolution in soft-collinear effective theory (SCET). Results are given for the scalar, vector and tensor form-factors for fermion and scalar particles. The formalism for including massive gauge bosons in SCET is developed.
