Search for contact interactions and large extra dimensions in the dilepton channel using proton-proton collisions at √s = 8 TeV with the ATLAS detector
A search, performed using the ATLAS experimental data, is conducted for non-resonant new phenomena in the dilepton final state, which could originate from contact interactions and large extra spatial dimensions. The full LHC 2012 proton-proton dataset is used comprising 21 fb−1 at s√ = 8 TeV, record...

Sumario: | A search, performed using the ATLAS experimental data, is conducted for non-resonant new phenomena in the dilepton final state, which could originate from contact interactions and large extra spatial dimensions. The full LHC 2012 proton-proton dataset is used comprising 21 fb−1 at s√ = 8 TeV, recorded by the ATLAS detector under nominal conditions. For the first time in ATLAS, forward-backward asymmetry was used as a search variable where relevant, in addition to invariant mass, to increase the search sensitivity to the new physics models under investigation. |
