Search for anomalous production of prompt same-sign lepton pairs and pair-produced doubly charged Higgs bosons with s =8 TeV pp collisions using the ATLAS detector

Abstract: A low-background inclusive search for new physics in events with same-sign dileptons is presented. The search uses proton-proton collisions corresponding to 20.3 fb −1 of integrated luminosity taken in 2012 at a centre-of-mass energy of 8 TeV with the ATLAS detector at the LHC. Pairs of is...
