Query: The Two-Photon Decay Mode of MSSM Higgs Bosons at the Large Hadron
  Collider   At the Large Hadron Collider (LHC), the CP-even Higgs bosons ($h^0$ and
$H^0$) of the Minimal Supersymmetric Standard Model (MSSM) will be searched for
mainly through their two-photon decay. We present a detailed analysis of the
production and two-photon decay of the CP-even Higgs bosons of MSSM at the LHC
by taking into account all the parameters of the model, especially the bilinear
parameter $\mu$ and the trilinear supersymmetry breaking parameter $A$.
Non-zero values of these parameters lead to significant mixing in the squark
sector, and, thus, affect the masses of Higgs bosons through radiative
corrections, as well as their couplings to squarks. The dependence of the cross
section for the production of Higgs, and its subsequent decay to two photons,
on various parameters of the MSSM is described in detail. The cross section
times the two-photon branching ratio of $h^0$ is of the order of 15--25~fb in
much of the parameter space that remains after imposing the present
experimental constraints on the parameters. For the $H^0$, the two-photon
branching ratio is only significant if it is light. With a light $H^0$ the
cross section times the branching ratio may be 200~fb or more.
