Description
Recent years, the intensity frontier of physics beyond the Standard model attracts more and more attentions. Thus light long lived particles searches becomes critical, and the various new machines like FASER, ShiP, Mathusla are built up or proposed. In this talk we study the prospect of detecting light long-lived Higgs at these machines. We develop the general formalism for the scalar production and decay from mesons at LHC, given modified couplings of the scalars to the SM particles, as well as summarizing the relevant GeV-scale experiment constraints. We then analyze the light scalars in the framework of the Type-I 2HDM and MSSM. We finally try to figure out how to detect LLPs beyond the typical limit of FASER detector.
