A Heavy Scalar at the LHC from Vector Boson Fusion

Abstract

A hypothetical scalar mixed with the standard model Higgs appears in few contexts of new physics. This study addresses the question what mass range is in the reach of $14$ TeV LHC given different magnitudes of mixing angle $\alpha$, where event simulations are based on production from vector boson fusion channel and decays into SM leptons through $\mathrm{WW}$ or $\mathrm{ZZ}$. It indicates that heavy scalar mass up to $539$ GeV and $937$ GeV can be excluded by integrated luminosity of $300$ ${\mathrm{fb}}^{-1}$ and $3000$ ${\mathrm{fb}}^{-1}$ respectively for ${\sin }^2\alpha$ larger than $0.04$.
