Inclusive Higgs boson cross-section for the LHC at 8 TeV

Charalampos Anastasiou, Stephan Buehler, Franz Herzog, Achilleas Lazopoulos

摘要:

本文给出了碰撞能量为8 TeV的LHC中包含的希格斯玻色子截面。我们的预测是使用我们的公开程序iHixs,其中包括NNLO QCD修正和电弱修正。我们回顾收敛的QCD微扰膨胀在这个新的能源和研究有限希格斯宽度效应的影响。我们还研究了不同部分子分布函数对截面的影响。我们目前的表格与截面值和估计其不确定性,由于未计算的高阶微扰膨胀和部分子密度。

英文摘要:

We present the inclusive Higgs boson cross-section at the LHC with collision energy of 8 TeV. Our predictions are obtained using our publicly available program iHixs which incorporates NNLO QCD corrections and electroweak corrections. We review the convergence of the QCD perturbative expansion at this new energy and examine the impact of finite Higgs width effects. We also study the impact of different parton distribution functions on the cross-section. We present tables with the cross-section values and estimates for their uncertainty due to uncalculated higher orders in the perturbative expansion and parton densities.
