This model has four types, which are Type-I, Type-II, Type-X (lepton specific) and Type-Y (Flipped). We discuss the Madala hypothesis as a Type-II two Higgs doublet model, where the Madala hypothesis introduces the Madala boson (which is a doublet-like heavy Higgs boson) with mH = 270 GeV. We study the Madala boson in the proposed LHeC, which is a ep collider. The Madala boson has a higher crosssection in the LHeC with proton beam energy of Ep = 7 TeV in the charge current and the neutral current is suppressed.Online resource (vi, 85 leaves)enLarge Hadron Collider (France and Switzerland)Particles (Nuclear physics)Thesis
