- Abstract
- A large number of top quarks will be produced at the Large Hadron Collider (LHC) during the Run II period. This will allow us to measure the rare processes from the top sector in great details. We present a study of top-quark pair production in association with a bottom-quark pair () from fast simulations for the Compact Muon Solenoid (CMS) experiment. The differential distributions of are compared with the top-quark pair production with two additional jets () and with the production in association with the Higgs (), where the Higgs decays to a bottom-quark pair. The significances of the process in the dileptonic and the semileptonic decay modes are calculated with the data corresponding to an integrated luminosity of 10 fb(-1), which is foreseen to be collected in the early Run II period. This study will provide an important input in searching for new physics beyond the standard model, as well as in searching for the process where the Yukawa coupling with the top quark can be directly measured.
