 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.

 CMS measurements of rare B meson decays to two muons / Kovalskyi, Dmytro (MIT) /CMS Collaboration We report a measurement of the ${\rm B^0_s}\to\mu^+\mu^-$ branching fraction and its effective lifetime, as well as results of a search for the ${\rm B}^0\to\mu^+\mu^-$ decay in proton-proton collisions at $\sqrt{s}=13~\rm{TeV}$ at the LHC. The analysis is based on data collected with the CMS detector in 2016-2018 corresponding to an integrated luminosity of $140~{\rm fb}^{-1}$. [...] CMS-CR-2022-251.- Geneva : CERN, 2022 - 7 p.

 Search for Dark Matter with mono-X Signatures in CMS / Deepak Kumar /CMS Collaboration Searches in CMS for dark matter in final states with invisible particles recoiling against visible states are presented. Various topologies and kinematic variables are explored, including jet substructure as a means of tagging heavy bosons. [...] CMS-CR-2022-249.- Geneva : CERN, 2022 - 7 p.

 Search for resonant and nonresonant di-Higgs boson production at CMS using jet substructure techniques / D'Amante, Valeria (INFN, Pisa) /CMS Collaboration The measurement of pair-production of Higgs bosons is one of the key goals of the LHC. Also, beyond the standard model theories involving extra spatial dimensions predict resonances with large branching fractions in a pair of Higgs bosons with negligible branching fractions to light fermions.

 The GEM GE1/1 station of the CMS muon detector status, commissioning and operation in magnetic field. / Mittal, Monika (BeiHang U.) /CMS Collaboration During Run 3, the LHC will deliver instantaneous luminosity in the range $5\times10^{34} cm^{-2} s^{-1}$ to $7 \times 10^{34} cm^{-2} s^{-1}$. To cope with the high background rates and to improve the trigger capabilities in the forward region, the muon system of the CMS experiment has been upgraded with two new stations of detectors (GE1/1), one in each endcap, based on triple-GEM technology.

 New Slow Control Emulator for the CMS Phase-2 Upgrade RPC Link System / Boghrati, Behzad (IPM, Tehran) /CMS Collaboration The CERN Compact Muon Solenoid (CMS) RPC system phase-2 upgrade project is in good progress. It covers the replacement of the off-detector electronics for the present Resistive Plate Chambers (RPC), known as "link system", and includes the renovation of the legacy slow controller with brand new electronics, called RPC backend electronics.

 96-channel Time-to-Digital converter (TDC) for the RPC Phase-2 Link System / Boghrati, Behzad (IPM, Tehran) /CMS Collaboration The phase-2 upgrade of the CMS RPC System for the low-eta region will enhance the electronics performance and muon hit time resolution to cope with the High Luminosity Large Hadron Collider (HL-LHC) conditions. In the Compact Muon Solenoid (CMS) experiment, Resistive Plate Chambers (RPC) have between 36 and 96 strips read out by frontend electronics boards (FEB).

 Results from angular analyses of B-meson decays in CMS / Boletti, Alessio (LIP, Lisbon) /CMS Collaboration The rare flavour-changing neutral current decays of the B mesons are among the most sensitive laboratories to probe the Standard Model and indirectly search for physics beyond it. In this report, a complete review of the analyses of the rare $b\to s\ell\ell$ decays performed by the CMS Collaboration is presented. [...] CMS-CR-2022-243.- Geneva : CERN, 2022 - 7 p.
