QCD中三阶阈值Drell-Yan和Higgs产生的快度分布

Rapidity Distributions in Drell-Yan and Higgs Productions at Threshold to Third Order in QCD

Taushif Ahmed, M. K. Mandal, Narayan Rana, V. Ravindran

摘要:

给出了Drell-Yan过程中双轻子和胶子融合中希格斯玻色子快度分布的阈值N $^3$ LO微扰QCD修正. QCD振幅的Sudakov重定、重整化群不变性和质量因子分解定理提供了有用的指导,以优雅的方式获得它们。我们使用各种国家的最先进的三个循环的结果,最近已获得这些分布。对于希格斯玻色子,我们证明了数值的重要性,这些修正在大型强子对撞机。

英文摘要:

We present the threshold N$^3$LO perturbative QCD corrections to the rapidity distributions of dileptons in the Drell-Yan process and Higgs boson in gluon fusion. Sudakov resummation of QCD amplitudes, renormalization group invariance, and the mass factorization theorem provide useful guidelines to obtain them in an elegant manner. We use various state of the art three loop results that have been recently available to obtain these distributions. For the Higgs boson, we demonstrate numerically the importance of these corrections at the LHC.
