Title: Search for non-SM Light Higgs Boson in the $h \to \gamma \gamma$ Channel

Author: Alex Melnitchouk

A search for non-SM light Higgs boson with an enhanced branching fraction
into photons in $p \bar{p}$ collisions
at the Fermilab Tevatron is presented 
using Run II D\O\ data taken between April 2002 and September 2003.
We set 95\% CL limits on the diphoton branching fraction as a function
of Higgs mass for Fermiophobic and Topcolor Higgs scenarios. Our current sensitivity
is comparable with that of Run I.
The results are consistent with previous version of the analysis in Run II.
Recent developments in Photon ID improve the sensitivity to $h \to \gamma \gamma$ signal
in addition to the increase in the integrated luminosity.
