Study of heavy-flavor quarks produced in association with top-quark pairs at root s=7 TeV using the ATLAS detector

Abstract:

Using a sample of dilepton top-quark pair (tt̄) candidate events, a study is performed of the production of top-quark pairs together with heavy-flavor (HF) quarks, the sum of tt̄+b+X and tt̄+c+X, collectively referred to as tt̄+HF. The data set used corresponds to an integrated luminosity of 4.7fb-1 of proton-proton collisions at a center-of-mass energy of 7 TeV recorded by the ATLAS detector at the CERN Large Hadron Collider. The presence of additional HF (b or c) quarks in the tt̄ sample is...
