ATLAS search for new phenomena in dijet mass and angular distributions using pp collisions at √s = 7 TeV

Mostrar todas las versiones(2)

Mass and angular distributions of dijets produced in LHC proton-proton collisions at a centre-of-mass energy √s = 7TeV have been studied with the ATLAS detector using the full 2011 data set with an integrated luminosity of 4.8 fb -1 . Dijet masses up to ~ 4.0TeV have been probed. No resonance-like f...
