Probing a long-lived pseudoscalar in type-I 2HDM with displaced vertices and jets at the LHC
Lei Wang, Zeren Simon Wang, Haotian Xu
In the type-I two-Higgs-doublet model, the pseudoscalar can act as a long-lived particle (LLP) for sufficiently large values of . At the LHC, the particles are predo…

95 GeV Higgs boson and nano-Hertz gravitational waves from domain walls in the N2HDM
Haotian Xu, Yufei Wang, Xiao-Fang Han +1
We explore the diphoton and excesses at 95.4 GeV, as well as nano-Hertz gravitational waves originating from domain walls, within the framework of the next-to-two-Higgs-…

A 95 GeV Higgs boson and spontaneous CP-violation at the finite temperature
Jing Gao, Jinghong Ma, Lei Wang +1
The ATLAS and CMS collaborations reported a diphoton excess in the invariant mass distribution around the 95.4 GeV with a local significance of . Moreover, there is another $…
