NNLO对VBF希格斯玻色子产生的修正

NNLO corrections to VBF Higgs boson production

Juan Cruz-Martinez, Nigel Glover, Thomas Gehrmann, Alexander Huss

摘要:

这次演讲扩展了最近发表的结果,因子分解次-次-领先阶(NNLO)QCD校正矢量玻色子融合(VBF)通道中的希格斯玻色子生产。计算是完全差分的希格斯玻色子和最终状态喷流的运动学,并在NNLOJET框架计算高阶QCD修正。我们发现NNLO修正的大小被限制在约$\pm 5$ \%,在横向动量和两个标签喷流的快度分离的运动学依赖性弱。

英文摘要:

This talk expands on recently published results for the factorising next-to-next-to-leading order (NNLO) QCD corrections to Higgs boson production in the vector boson fusion (VBF) channel. The calculation is fully differential in the kinematics of the Higgs boson and the final state jets and is implemented in the NNLOJET framework for computing higher-order QCD corrections. We find the NNLO corrections to be limited in magnitude to about $\pm 5$\% with a weak kinematical dependence in the transverse momenta and rapidity separation of the two tagging jets.
