Top quark events are abundantly produced in LHC collisions. They are used to look for crucial signals of physics beyond the SM, as well as tools to improve our understanding of QCD and modelling of proton collisions. Top quark events also provide a source of high energy bottom quarks, providing a fertile ground for b-hadron studies, complementary to those done at LHCb or B factories. In this seminar we report on a recent measurement of charge and Charge-Parity asymmetries of b-hadron decays using top quark events by ATLAS using the 8 TeV LHC dataset. Comparison of the results are made with similar asymmetries measured by D0 and LHCb.
