在未来轻子对撞机上共振Higgs产生的ISR效应

ISR effects for resonant Higgs production at future lepton colliders

Mario Greco, Tao Han, Zhen Liu

摘要:

通过与对撞机的束流能量分布和信号的Breit-Wigner共振分布进行卷积,研究了初态辐射对$μ^+μ^-$和$e^+e^-$对撞机上$s$通道希格斯玻色子共振产生的影响.我们评估它们对希格斯信号和SM背景的主要衰变通道$h\rightarrow b\bar b,\ WW^*$的影响。我们的研究改进了现有的分析建议未来的共振希格斯工厂,并提供了进一步的指导加速器设计方面的物理目标。

英文摘要:

We study the effects of the initial state radiation on the $s$-channel Higgs boson resonant production at $μ^+μ^-$ and $e^+e^-$ colliders by convoluting with the beam energy spread profile of the collider and the Breit-Wigner resonance profile of the signal. We assess their impact on both the Higgs signal and SM backgrounds for the leading decay channels $h\rightarrow b\bar b,\ WW^*$. Our study improves the existing analyses of the proposed future resonant Higgs factories and provides further guidance for the accelerator designs with respect to the physical goals.
