授课摘要
The ForwArd Search ExpeRiment (FASER), is a recently installed detector at the Large Hadron Collider (LHC) that can detect light, long lived particles. The talk will introduce the latest status of FASER, as well as other latest study results about the photon and dark photon models. About the FASER, we study the prospect of detecting light CP-even and CP-odd scalars at the FASER. 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 reaches of light scalars in the large $\tan\beta$ region of the Type-I 2HDM, in which a light scalar with relatively long lifetime could be accommodated.
In a summary, I will introduce the latest theoretical and experimental studies about the photon and dark photon study in the field of theoretical physics, and extend to the future collider physics.
