Portal to non-MSSM models using kinematic edges

Speaker : Dr. Abhishek Iyer TIFR, Mumbai.


Abstract :

A heavy Higgs like resonance (H1) is a characteristic feature of many new physics scenarios beyond the Standard Model (SM). In the event of a discovery it is essential to identify the true nature of physics beyond the SM. In this work we propose a channel, H1 -> t2t, where t2 is a vector like gauge singlet top- partner. t2 may further decay into Wb, Zt, ht. We construct different invariant mass distributions which are characterized by the presence of kinematic edges, unique to the topology under consideration. The absence of these vector like states in minimal versions of supersymmetric models also serves as a smoking towards the presence of non MSSM like scenarios. Using these kinematic edges, the masses of the heavy resonances can be extracted up-to a reasonable accuracy. Observation of these features are meant to serve as a trigger, thereby mandating a more detailed analysis in a particular direction of parameter space.
