我们提出了希格斯双光子信号与大型强子对撞机连续背景之间干涉效应的完整 O (α 2S ) 计算。虽然干扰的主要贡献源自 gg 部分子过程,但我们发现来自 qg 和 q ¯ q 通道的修正量高达 35%。我们讨论了这些新子过程对 S. Martin 最近报道的双光子不变质量峰移动的影响 (Phys. Rev. D 86:073016, 2012)。
We present the full O (α 2S ) computation of the interference effects between the Higgs diphoton signal and the continuum background at the LHC. While the main contribution to the interference originates on the gg partonic subprocess, we find that the corrections from the qg and q ¯ q channels amount up to 35 % of it. We discuss the effect of these new subprocesses in the shift of the diphoton invariant mass peak recently reported by S. Martin in (Phys. Rev. D 86:073016, 2012).
