给出了大型强子对撞机上希格斯双光子信号与连续本底干涉效应的全O(�2)计算。虽然对干扰的主要贡献来自于gg分立子过程,但我们发现来自qg和qq通道的校正高达35%。我们讨论了这些新的子过程在S.Martin最近在文献[1]中报道的双光子不变质量峰移动中的作用。[1]。
We present the full O(� 2 ) 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 Ref. [1].
