Limits on the production of the standard model Higgs boson in pp collisions at √s=7 TeV with the ATLAS detector

Mostrar todas las versiones(2)

A search for the Standard Model Higgs boson at the Large Hadron Collider (LHC) running at a centre-of-mass energy of 7 TeV is reported, based on a total integrated luminosity of up to 40 pb -1 collected by the ATLAS detector in 2010. Several Higgs boson decay channels: H→γγ, H→ZZ (*) →ℓℓℓℓ, H→ZZ→ℓℓν...
