LHC运行I后SUSY模型中的hhh偶联

hhh Coupling in SUSY models after LHC run I

Lei Wu, Jin Min Yang, Chien-Peng Yuan, Mengchao Zhang

摘要:

我们研究了在电流约束下MSSM和NMSSM中的Higgs三重耦合,其中包括LHC测量、Higgs数据、B物理、电弱精密观测量、遗迹密度等,由于参数空间的高度约束,其比值$λ^{\rm MSSM}_{hhh}/λ^{\rm SM}_{hhh}$大于0.97。而比率$λ^{\rm NMSSM}_{hhh}/λ^{\rm SM}_{hhh}$在电流约束下可以达到0.1。未来对撞机的精确测量将对MSSM和NMSSM中的Higgs三重耦合给出更严格的约束。

英文摘要:

We examine the Higgs triple coupling in MSSM and NMSSM under current constraints, which include the LHC measurements, Higgs data, B physics, electroweak precision observables, relic density and so on. The ratio $λ^{\rm MSSM}_{hhh}/λ^{\rm SM}_{hhh}$ is above 0.97, due to the highly constrained parameter space. While the ratio $λ^{\rm NMSSM}_{hhh}/λ^{\rm SM}_{hhh}$ can reach 0.1 under current constraints. The precise measurement in future collider will give a tighter constraint to the Higgs triple coupling in MSSM and NMSSM.
