Oblique parameters in gauged baryon and lepton numbers with a 125GeV   Higgs
  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 $h_0$ with mass around $124-126{\rm GeV}$ strongly constrains the corresponding parameter space of this model, we also investigate the gluon fusion process $gg\rightarrow h_0$ and two photon decay of lightest neutral Higgs $h_0\rightarrow\gamma\gamma$ at the Large Hadron Collider.
