We perform an exclusive search for the Higgs boson to gamma-gamma decay via vector boson fusion. We utilize the characteristic features of vector boson fusion, such as the di-jet [Delta][eta] and mass, as well as the di-photon [rho][tao], to search for the Higgs boson to gamma-gamma decay via the vector boson fusion process. The theoretical production cross section limit is analyzed over the accepted possible mass range for the Higgs boson, 120-130 GeV/c 2 . We are able to reduce the theoretical production cross section limit to ~ 6[sigma]SM in this range by using a boosted decision tree. Comparison to the cut based approach used by the CMS Collaboration shows no improvement in using a BDT as opposed to a cut based approach.
