再论125 GeV希格斯玻色子与光子在希格斯工厂的关联产生

Revisiting Associated Production of 125 GeV Higgs Boson with a Photon at a Higgs Factory

Song Lin Hu, Ning Liu, Jie Ren, Lei Wu

摘要:

考虑到味物理、精密电弱测量、Higgs数据和暗物质探测的约束,我们扫描了MSSM的参数空间,并在允许的参数空间内计算了$e^+e^- \to h γ$的截面.由于环致规范耦合$hγγ$和$hZγ$可以同时对过程$e^+e^- \to h γ$做出贡献,因此我们发现横截面可以通过光态大幅增强,最大比在$\sqrt{s}=240(350)$ GeV处的SM预测大1.47(1.38)倍。因此,在高光度下,$e^+e^- \to h γ$的测量可以用来检验Higgs工厂MSSM中的反常规范耦合$hγγ$和$hZγ$。

英文摘要:

Considering the constraints from the flavor physics, precision electroweak measurements, Higgs data and dark matter detections, we scan over the parameter space of the MSSM and calculate the cross section of $e^+e^- \to h γ$ in the allowed parameter space. Since the loop-induced gauge couplings $hγγ$ and $hZγ$ can simultaneously contribute to the process $e^+e^- \to h γ$, we find the cross section can be sizably enhanced by a light stau, maximally 1.47(1.38) times larger than the SM prediction at $\sqrt{s}=240(350)$ GeV. So with the high luminosity, the measurement of $e^+e^- \to h γ$ may be used to test the anomalous gauge couplings $hγγ$ and $hZγ$ in the MSSM at a Higgs Factory.
