A Heavy Scalar at the LHC from Vector Boson Fusion
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 $α$, where event simulations are based on production from vector boson fusion channel and decays into SM leptons through ${\rm WW}$ or ${\rm ZZ}$. It indicates that heavy scalar mass up to $539$ GeV and $937$ GeV can be excluded by integrated luminosity of $300$ $\rm{fb}^{-1}$ and $3000$ $\rm{fb}^{-1}$ respectively for $\sin^{2}α$ larger than $0.04$.
