纵向和横向规范玻色子和Higgs产生的辐射修正

Radiative Corrections to Longitudinal and Transverse Gauge Boson and Higgs Production

Andreas Fuhrer, Aneesh V. Manohar, Jui-yu Chiu, Randall Kelley

摘要:

最近用软共线有效理论(SCET)计算的规范玻色子和Higgs产生的辐射修正需要标准模型中的单圈高尺度匹配系数。对于具有任意数量规范群的一般规范理论,我们给出了当qqbar-> VV和qqbar-> phi^+ phi时有效场论(EFT)算符匹配系数的显式表达式.明确给出了标准模型的群论因子,包括QCD和电弱修正。

英文摘要:

Radiative corrections to gauge boson and Higgs production computed recently using soft-collinear effective theory (SCET) require the one-loop high-scale matching coefficients in the standard model. We give explicit expressions for the matching coefficients for the effective field theory (EFT) operators for q qbar -> VV and q qbar -> phi^+ phi for a general gauge theory with an arbitrary number of gauge groups. The group theory factors are given explicitly for the standard model, including both QCD and electroweak corrections.
