We present a search for the standard model Higgs boson and a fermiophobic Higgs boson in the diphoton final states based on 8.2fb-1 of pp̄ collisions at √s=1.96TeV collected with the D0 detector at the Fermilab Tevatron Collider. No excess of data above background predictions is observed and upper limits at the 95% C.L. on the cross section multiplied by the branching fraction are set which are the most restrictive to date. A fermiophobic Higgs boson with a mass below 112.9 GeV is excluded at the 95% C.L. © 2011 American Physical Society.
