Search for the standard model and a fermiophobic Higgs boson in diphoton final states

Understand

We present a search for the standard model Higgs boson and a fermiophobic Higgs boson in the diphoton final states based on 8.2 fb-1 of ppbar collisions 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.
