چکیده انگلیسی
The CMS trigger stands for the daunting task of selecting rare signal processes amidst the 40 million bunch crossings. While the tracker information is not available in the first level of the trigger, it plays a crucial role in the high-level trigger. In this contribution, the ττ and b identification performance in the trigger is discussed. Hadronic ττ decays can efficiently be reconstructed and selected using tracker information. An inclusive b-jet trigger based on a lifetime tag allows the jet thresholds to be significantly reduced, thus providing a very much improved trigger efficiency for hadronic final states with b-quarks, such as hadronically decaying top pairs.
