Interference between the Standard Model Higgs Boson and the Beyond Standard Model and Its Dependence on the Kinetic Variable
Abstract: The experimentally observed coupling scale factor for the SM particles (k) being > 1 (BRnew = 0: 43), a new Higgs scalar is introduced for unitarity at very high energy. The new Higgs scalar cannot be constrained by the measurement of on-shell and off-shell cross section for masses < 350 GeV. The interference technique which depends on the relative sign of the couplings of the interfering particles is the best method for constraining Higgs width and predicting the new physics particles beyond the energy scale of present day LHC. Here, we study the interference between the Higgs decay channel bb initiated by the gluon fusion.
