Abstract：
In an extension of the standard model, where baryon number and lepton number are local gauge symmetries, we analyze the effect of corrections from exotic fermions and scalars on the oblique parameters S, T, U. Because a light neutral Higgs h₀ with mass around 124—126GeV strongly constrains the corresponding parameter space of this model, we also investigate the gluon fusion process gg→h₀ and two photon decay of the lightest neutral Higgs h₀→γγ at the Large Hadron Collider.
