Description
The connection between the multi-lepton anomalies at the Large Hadron Collider and astrophysics can be described by a two Higgs doublet model with an additional singlet scalar (2HDM+S). We make studies on the interaction mechanism of singlet S to dark matter. This is achieved from the annihilation of Dark Matter (DM). We demonstrate that using this model we could also describe the excesses in gamma-ray flux from the galactic centre and the cosmic-ray spectra from AMS-02. Moreover, this study provides indirect searches for new bosons that have never been performed before at the LHC, namely the search for H→SS,S→invisible and S decaying into other particles.
