Certain extended supersymmetric theories can accommodate light
scalar(s),
pseudoscalar(s) and neutralino(s) in some regions of the parameter
space.
These states, through their presence in the decay cascades of the
heavier
particles can lead to novel signatures at the LHC. We emphasise how the
presence of these states produces distinct final states at the LHC from
the
decays of heavier standard model particles, like W± , Z as well as
Higgs boson.
An analysis of this kind is a viable choice to verify evidence of new
physics beyond the standard model when the rest of the mass spectrum
remains beyond the reach of the LHC, following the trend of missing
excess
over the standard model prediction as of now. We exemplify our analysis
with the μνSSM, where three families of the right-handed neutrino
superfields
have been used to offer a solution to the μ-problem and at the same
time to house the observed three flavour neutrino data. |
