“…With this prodigious high-energy proton collisions rate, efficient triggering on electrons and photons has become a major challenge for the LHC experiments. The Compact Muon Solenoid (CMS) experiment implements a sophisticated two-level online selection system that achieves a rejection factor of nearly 106. …”

“…We present a study of top-quark pair production in association with a bottom-quark pair ( $t\bar tb\bar b$ ) from fast simulations for the Compact Muon Solenoid (CMS) experiment. The differential distributions of $t\bar tb\bar b$ are compared with the top-quark pair production with two additional jets ( $t\bar tjj$ ) and with the production in association with the Higgs ( $t\bar tH$ ), where the Higgs decays to a bottom-quark pair. …”
