Search for a fermiophobic Higgs boson in the diphoton decay channel with the ATLAS detector

Mostrar todas las versiones(2)

A search for a fermiophobic Higgs boson using diphoton events produced in proton-proton collisions at a centre-of-mass energy of √ s = 7 TeV is performed using data corresponding to an integrated luminosity of 4.9 fb−1 collected by the ATLAS experiment at the Large Hadron Collider. A specific benchm...
