在未来轻子-质子对撞机上对Higgs产生的次领先级QCD修正

Next-to-leading order QCD corrections to Higgs production at a future lepton-proton collider

B. Jager

摘要:

关于希格斯玻色子与底夸克耦合的关键信息,预计将从未来高能轻子-质子对撞机上与前向标记喷流相关的希格斯产生中获得。为了控制信号过程的理论不确定性,必须量化辐射校正的影响。本文给出了对e-p-> e-jH和e-p-> nu_ejH的次领先阶QCD修正,并给出了一个灵活的Monte-Carlo程序,该程序允许在实验上可行的选择切割范围内计算截面和运动学分布。对截面的QCD修正很小,而分布的形状畸变可达20%。次领先阶的剩余标度不确定性处于千分之一水平。

英文摘要:

Crucial information on the coupling of the Higgs boson to bottom quarks is expected from Higgs production in association with a forward tagging jet at a future high-energy lepton-proton collider. In order to control the theoretical uncertainties of the signal process, the impact of radiative corrections has to be quantified. We present the full next-to-leading order QCD corrections to e- p -> e- j H and e- p -> nu_e j H in the form of a flexible Monte-Carlo program allowing for the calculation of cross sections and kinematic distributions within experimentally feasible selection cuts. QCD corrections are found to be very small for cross sections, while the shape distortion of distributions can be as large as 20%. Residual scale uncertainties at next-to-leading order are at the permille level.
