Abstract :

I will discuss the prospects of reconstructing the mass of the scalars in the context of a Type X two-Higgs doublet model where a light pseudoscalar A in the mass range 40 - 60 GeV is phenomenologically allowed, and is in fact favoured if one wants to explain the muon anomalous magnetic moment. I will discuss how to reconstruct the pseudoscalar. On the other hand the associated production of charged Higgs with the pseudoscalar A and subsequent decay of the charged Higgs into a W and A, is found to be helpful in identifying the charged Higgs. The neutral heavy Higgs, being degenerate with the charged Higgs for most of the allowed parameter space of the model, also contributes to similar final states. Thus, it is possible to reconstruct both the charged and neutral CP-even heavy Higgs bosons within a band of about 10 GeV.
