750 GeV双光子过剩:谁介绍的?

The 750GeV diphoton excess: who introduces it?

Hao Zhang

摘要:

最近,ATLAS和CMS合作报告了在13 TeV LHC的双光子不变质谱中在750 GeV处的过量。如果它是一个新的标量,通过环引起的胶子-胶子熔合过程产生的,那么知道环中的粒子是什么就很重要了。在这项工作中,我们探讨了确定圈中标准模型顶夸克贡献的可能性。

英文摘要:

Recently, both ATLAS and CMS collaborations report an excess at 750GeV in the diphoton invariant mass spectrum at 13TeV LHC. If it is a new scalar produced via loop induced gluon-gluon fusion process, it is important to know what is the particle in the loop. In this work, we investigate the possibility of determine the fraction of the contribution from the standard model top-quark in the loop.
