强子对撞机上H-> WW ->l nu l nu信号的QCD辐射效应

QCD Radiation Effects on the H->WW->l nu l nu Signal at Hadron Colliders

Fabian Stoeckli

摘要:

当实验切割增加信号和背景截面的比例时,标准模型希格斯玻色子的发现是可能的。本文研究了在强子对撞机上pp->H->WW信号截面,这需要选择具有小横动量的希格斯玻色子。我们比较预测的效率的实验削减从NNLO QCD计算和事件发生器MC@NLO,并能够预测一个可靠的数字的横截面后application这样的实验削减。

英文摘要:

The discovery of a Standard Model Higgs boson is possible when experimental cuts are applied which increase the ratio of signal and background cross-sections. We present a study of the pp->H->WW signal cross-section at hadron colliders which requires a selection of Higgs bosons with small transverse momentum. We compare predictions for the efficiency of the experimental cuts from a NNLO QCD calculation and the event generator MC@NLO and are able to predict a reliable number for the cross-section after the aplpication of such experimental cuts.
