Since its discovery in 1995, top quark has remained as a hot topic in the realm of high energy physics (HEP). With a mass of about 180 higher than the proton mass, top quark is first known as its "fatness". It plays a special role in the Standard Model (SM) of particle physics as well as in searches for new physics beyond the SM.
Among many interesting top-quark related studies that have performed by the ATLAS experiment at the Large Hadron Collider, in this talk we present a cross section measurement of the top quark pair production in association with jets containing b-hadrons, using 20.3 fb^{-1} proton-proton collision data at a center-of-mass energy of 8 TeV. The measurement not only provides insights to understand the Quantum Chromodynamics, it also help optimize and constraint many possible searches for new physics beyond the SM.
