| 英文摘要 | We investigate the di-Higgs production at the Large Hadron Collider in the two-Higgs doublet model (2HDM). In particular, we study the production of an extra neutral Higgs boson phi in association with the Standard Model (SM) Higgs boson h in the Higgs alignment limit. We analyze two scenarios where the additional Higgs phi is in a CP-even or-odd state with a large top-Yukawa interaction. The leading contribution of this production comes from the top-quark loop-induced gluon-fusion channel gg -> h phi. The measurement of the h phi production can probe the quartic couplings in the Higgs potential as well as the top-Yukawa couplings. Imposing both theoretical constraints (from the perturbative unitarity and the vacuum stability bounds) and experimental bounds (from the SM Higgs and flavor physics measurements) on the 2HDM parameter space, we calculate the production cross section of gg -> h phi. Furthermore, we scrutinize these processes in the parameter spaces where the CMS ditau and diphoton excesses around 100 GeV, and/or the muon g - 2 anomaly can be accommodated. |
