A study of heavy-flavor quarks produced in association with top-quark pair events at a center-of-mass energy of 7 TeV using the ATLAS detector
In this thesis, we show evidence for the production of $t\bar{t} + b + X$ and $t\bar{t} + c + X$, together refered to as $t\bar{t} + \rm{HF}$, at the Large Hadron Collider. A sample of dilepton $t\bar{t}$ candidate events with three or more $b$-tagged jets is used to isolate a $t\bar{t}$ sample rich...
