摘要:

本文在软共线有效理论框架下研究了LHC产生大$p_T$希格斯玻色子玻色子的次-次-领先对数阶数重算。我们发现,在大的$p_T$区域,重算效应显著地降低了标度不确定性,使QCD非线性光学结果降低了约$11\%$。讨论了有限顶夸克质量效应和NNLO奇异项的影响。

英文摘要:

We study the next-to-next-to-leading logarithmic order resummation for the large $p_T$ Higgs boson production at the LHC in the framework of soft-collinear effective theory. We find that the resummation effects reduce the scale uncertainty significantly and decrease the QCD NLO results by about $11\%$ in the large $p_T$ region. The finite top quark mass effects and the effects of the NNLO singular terms are also discussed.
