在高能轻子对撞机上将矢量熔合成标量

Fusing Vectors into Scalars at High Energy Lepton Colliders

Dario Buttazzo, Diego Redigolo, Filippo Sala, Andrea Tesi

摘要:

研究了在高能轻子对撞机上新标量单态的矢量玻色子融合产生。我们发现CLIC有潜力测试几十个阿托班在双希格斯和双玻色子的最终状态的单生产截面。在具有相当大的单重态-希格斯混合的模型中,这些值对应于希格斯耦合的精度为0.1%或更高。我们比较我们的灵敏度与大型强子对撞机和解释我们的结果动机良好的模型,如双希格斯,NMSSM和轴子样粒子。展望更高能量的机器,我们表明,像LEMMA或MAP的μ子对撞机的范围超过了未来的强子机器之一,如FCC-hh。最后,我们研究了新的标量单态通过离壳希格斯粒子的对产生。这一过程并不消失的小混合,并将构成一个重要的探针模型产生一级电弱相变。

英文摘要:

We study vector boson fusion production of new scalar singlets at high energy lepton colliders. We find that CLIC has the potential to test single production cross-sections of a few tens of attobarns in di-Higgs and di-boson final states. In models with a sizeable singlet-Higgs mixing, these values correspond to a precision in Higgs couplings of order 0.1% or better. We compare our sensitivities with those of the LHC and interpret our results in well-motivated models like the Twin Higgs, the NMSSM and axion-like particles. Looking forward to even higher energy machines, we show that the reach of muon colliders like LEMMA or MAP overcomes the one of future hadron machines like FCC-hh. We finally study the pair production of the new scalar singlets via an off-shell Higgs. This process does not vanish for small mixings and will constitute a crucial probe of models generating a first order electro-weak phase transition.
