Searching evidences of new physics in the light of the μνSSM

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.
