Charged Higgs decay to $W^{\pm }$ and heavy neutral Higgs decaying into ${\tau }^{+}{\tau }^{-}$ in Georgi Machacek Model at LHC

Abstract

The CMS collaboration at the Large Hadron Collider (LHC) searched for a charged Higgs boson, in the mass range of 300 to 700 GeV, decaying into a $W^{\pm }$ boson and a heavy neutral Higgs boson of mass $200$ GeV, which successively decays into a pair of tau leptons, in proton-proton collisions at $\sqrt{s}=13$ TeV. In this letter, focusing on the Georgi-Machacek (GM) model, I discuss the parameter space, allowed by the theoretical and experimental constraints, for which the limits on this process obtained by the CMS can be accommodated. The study in this letter also shows that, for the choice of the parameters, the decay of the charged Higgs boson $H_3^{\pm }$ to $W^{\pm }$ and a heavy neutral Higgs boson H is preferred over the decay to any gauge boson and any other neutral or charged Higgs bosons. I also present the values of production cross-section times branching ratio for the decay of H to a pair of b-quarks at $\sqrt{s}=14$ TeV.
