Description
In this talk I will show our recent study about the LLP searches af FASER. There are two kinds of modes, with the production from the usual mesons, and from the PP collision directly.
For the meson production mode, we study the prospect of detecting light CP-even and CP-odd scalars. 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. We then analyze the complete long-lived particle of 2HDM at FASER.
For the PP collision, we take the compressed neutral Higgsino as examples. The results show the NLSP, as the LLP, can be probed up to 100 GeV scale.
