强子对撞机上希格斯玻色子玻色子和高Pt喷流产生的运动学关联

Kinematical correlations for Higgs boson plus High Pt Jet Production at Hadron Colliders

Peng Sun, C. -P. Yuan, Feng Yuan

摘要:

本文研究了强子对撞机产生的希格斯玻色子加高横动量喷注事件中QCD修正对运动学关联的影响。我们表明,在完整的一个回路的顺序,柯林斯-Soper-Sterman再表示形式主义可以应用于推导Sudakov形状因子,这是独立的射流发现算法。在希格斯玻色子玻色子和高Pt喷注的横动量几乎是背靠背产生的情况下,我们比较了重传计算和定阶预测的奇异性,发现两者完全一致.在大型强子对撞机的再热效应的现象学的重要性也被证明。

英文摘要:

We investigate the effect of QCD resummation to kinematical correlations in the Higgs boson plus high transverse momentum (Pt) jet events produced at hadron colliders. We show that at the complete one-loop order, the Collins-Soper-Sterman resummation formalism can be applied to derive the Sudakov form factor, which is found to be independent of jet-finding algorithm. We compare the singular behavior of resummation calculation to fixed order prediction in the case that Higgs boson and high Pt jet are produced nearly back-to-back in their transverse momenta, and find a perfect agreement. The phenomenological importance of the resummation effect at the LHC is also demonstrated.
