环诱导的$Hγγ$和$Hgg$顶点是否有新的粒子运行?

Is there new particle running in the loop-induced $Hγγ$ and $Hgg$ vertex?

Seungwon Baek, Xing-Bo Yuan

摘要:

环诱导的$Hgg$和$Hγγ$耦合在LHC的Higgs产生和衰变中起着重要的作用。这些顶点可以受到各种新物理学贡献的影响,包括新粒子,异常汤川耦合,等等。我们指出,希格斯信号强度的一些比率可以帮助解开新粒子的贡献从其他来源的新物理。

英文摘要:

Loop-induced $Hgg$ and $Hγγ$ coupling play an important role in the Higgs production and decay at the LHC. These vertices can be affected by various New Physics contributions, including new particles, anomalous Yukawa couplings, and so on. We point out some ratios of the Higgs signal strengths could help disentangle the contributions of new particles from other sources of New Physics.
