Light Higgs Searches

Also additional Higgs bosons much lighter than the state discovered at 125 GeV must be considered . Such bosons could be feasible e.g. in the context of the Next-to-Minimal Supersymmetric Model (NMSSM). We are investigating two such scenarios:
  • a pair of light Higgs boson could appear through the decay of the known Higgs boson at 125 GeV. If the mass of the light bosons is below the beauty threshold, each would decay dominantly into a pair of tau leptons.
  • a light Higgs boson below the Z mass could have reduced couplings to W and Z and thus be invisible to the previous searches performed at the LEP collider. Such bosons might then be visible in super-symmetric neutralino cascades only accessible at the LHC.
