 New trigger strategies for CMS during Run 3 / Fontanesi, Elisa (Boston U.) /CMS Collaboration The CMS experiment at the Large Hadron Collider (LHC) features a sophisticated two-level triggering system composed of the Level 1 (L1) trigger, instrumented by custom-design hardware boards, and the High Level Trigger (HLT), a software based trigger exploiting a complete event information and full detector resolution. The CMS L1 trigger relies on separate calorimeter and muon trigger systems that provide jet, e/$\gamma$, $\tau$, and muon candidates along with calculations of energy sums to the global trigger (GT), where selections are based on the candidate kinematics.

 Studies of top quark spin and polarization in CMS / Iemmi, Fabio (Beijing, Inst. High Energy Phys.) /CMS Collaboration We describe the latest results obtained by the CMS Collaboration on top quark spin and polarization properties. The top quark spin asymmetry is measured both targeting single-top quark production in the t-channel and single-top quark production in association with a Z boson.
