胶子诱导的弱玻色子融合

Gluon-Induced Weak Boson Fusion

Robert Harlander, Jens Vollinga, Marcus Weber

摘要:

计算了弱玻色子聚变(WBF)产生Higgs的胶子-胶子诱导项。形式上,这些是强耦合常数的NNLO。这是散射夸克之间发生非零色交换的最低阶,导致色场,从而导致出射喷流之间的额外强子活动。使用一组最小的削减,这些条款的数值影响是在百分比水平上的NLO率弱玻色子融合。应用所谓的WBF切割导致甚至更强的抑制,因此我们不期望这些颜色交换效应导致WFB信号的显著恶化。

英文摘要:

The gluon-gluon induced terms for Higgs production through weak boson fusion (WBF) are computed. Formally, these are of NNLO in the strong coupling constant. This is the lowest order at which non-zero color exchange occurs between the scattering quarks, leading to a color field and thus additional hadronic activity between the outgoing jets. Using a minimal set of cuts, the numerical impact of these terms is at the percent level with respect to the NLO rate for weak boson fusion. Applying the so-called WBF cuts leads to an even stronger suppression, so that we do not expect a significant deterioration of the WFB signal by these color exchange effects.
