Talk in Parallel Session at DIS2013 Electroweak Physics and Beyond the Standard Model WG3: Electroweak and Searches

Speaker

Jordan S Webster (University of Chicago (US))

Description

Various extensions of the Standard Model predict the existence of new types of quarks. We report on several search channels such as vector-like quarks decaying to a Higgs boson and a top quark or to a W boson and a b quark. The talk presents results from searches for new resonances decaying to a top-antitop pair, including the use of boosted top quark reconstruction techniques. These searches use the data sample recorded in 2012 at sqrt(s)=8 TeV centre-of-mass energy by the ATLAS experiment at the LHC.
