The Fat Higgs Model (FHM) is an extension of the Standard Model (SM) introduced to explain the physics at the electroweak scale. The Higgs sector of this contains two doublets, as in the Minimal Supersymmetric Standard Model (MSSM), plus an additional gauge singlet. There are three CP-even, two CP-odd and two degenerate charged Higgs bosons in the theory. The distinct feature of this model is the fact that the trilinear coupling λ, which controls the masses, is allowed greater than unity due to the fact that the Higgs bosons are composites of a set fundamental fermions. The mass of the lightest CP-even Higgs boson can be raised to as high as 450 GeV without resorting to any loop induced mass corrections. In this thesis the SM-like Higgs boson of the FHM is identified and its couplings, branching fractions and total width are studied. The possibility of distinguishing SM-like Higgs boson of the FHM from the Higgs boson of the SM at the Large Hadron Collider (LHC) is also examined for a benchmark set of the free parameters. It found, for the chosen set of free parameters, that the distinction can be made using: the total width measurement above a Higgs mass of 310 GeV at the 4-5 σ level, the rate of the qqH -> W+W- -> l±vjj process below a mass of 200 GeV at the 2 σ level and the WW decay width in the Higgs mass range 190 - 250 GeV at the 3 σ level.
