abstract

We determine the discovery potential of the Large Hadron Collider (LHC) at 13 TeV center-of-mass energy for a heavy scalar resonance in the dilepton channel. In particular, we consider the singlet-like heavy mass eigenstate of a mixed two Higgs doublet and scalar singlet model in the $U(1)_{B-L}$ extension of the Standard Model. We find that, despite the small coupling of the singlet scalar with the doublets, this heavy scalar can be discovered with 5$\sigma$ at the LHC with integrated luminosities of $\sim 300$ to $1400$ fb$^{-1}$ in the mass range between 500 GeV and 1 TeV.

  1. MeV neutrino dark matter: Relic density, lepton flavour violation and electron recoil

    hep-ph 2019-08 accept novelty 6.0 of 10

    In the SLIM model, lepton flavour violation experiments like MEG exclude most of the parameter space that fits the dark matter relic density, making electron recoil detection hopeless.
