 Recent results in the H- gt WW channel with CMS / Ceccarelli, Rudy (INFN, Florence ; Florence U.) /CMS Collaboration Recent results on the cross section measurement of the Higgs boson production in association with a leptonically decaying vector boson are presented. Events where the Higgs boson decays to a pair of W bosons are considered for this analysis, with at least one vector boson decaying leptonically. [...] CMS-CR-2021-121.- Geneva : CERN, 2020 - 6 p.

 Searches for new physics in lepton and missing transverse momentum final states in CMS / Bachiller, Irene (Madrid, CIEMAT) /CMS Collaboration Many theories beyond the Standard Model (BSM) predict the existence of new, heavy resonances that may decay in leptonic final states. This talk presents the search for physics BSM in final states with an electron or muon, and missing transverse momentum. [...] CMS-CR-2021-050.- Geneva : CERN, 2021 - 5 p.

 Precision Timing with the CMS MTD Endcap Timing Layer for HL-LHC / Sola, Valentina (INFN, Turin) /CMS Collaboration The CMS MIP Timing Detector (MTD) is designed to provide precise timing information targeting a system-level resolution of $\sim$ 40 ps per layer for charged particles. The MTD provides near-hermetic coverage up to a pseudo-rapidity of $\mid \eta \mid =$ 3 and will comprise a barrel and two endcap detectors. [...] CMS-CR-2020-273.- Geneva : CERN, 2021 - 11 p.

 Precision Timing in the CMS MTD Barrel Timing Layer with Crystal Bars and SiPMs / Santanastasio, Francesco (INFN, Rome ; Rome U.) /CMS Collaboration The Compact Muon Solenoid (CMS) detector at the CERN Large Hadron Collider (LHC) is undergoing an extensive Phase II upgrade program to prepare for the challenging conditions of the High-Luminosity LHC (HL-LHC). In particular, a new timing layer will measure minimum ionizing particles (MIPs) with a time resolution of 30-40 ps and hermetic coverage up to a pseudo-rapidity of 3.

 Prospects for di-Higgs measurements in the $\mathrm{b\bar{b}\gamma\gamma}$ final state at the High-Luminosity LHC with the Phase-II CMS detector / Monti, Fabio (Beijing, Inst. High Energy Phys.) /CMS Collaboration The prospects for the study of the production of a pair of Higgs bosons, where one decays into two photons and the other one into a bottom quark-antiquark pair, are presented for center-of-mass energy of 14 TeV at the High-Luminosity LHC. The analysis is developed using a parametric simulation of the PhaseII upgraded CMS detector and optimized for an integrated luminosity of 3000 fb$^{-1}$.

 CP measurement of the Higgs-tau coupling / Hassanshahi, Mohammad Hassan (Department of Physics • Imperial College) /CMS Collaboration The Standard Model predicts that the Higgs boson is even under charge-parity inversion. In this report, we explain the result of the first direct measurement of the CP structure of the Yukawa coupling between the Higgs boson and tau leptons.

 CMS measurements of EFT parameters with top quarks / Tonon, Nicolas (DESY) /CMS Collaboration Measurements carried out or reinterpreted within the framework of effective field theory (EFT) will constitute a key component of the LHC legacy in the quest towards physics beyond the standard model. Numerous EFT measurements were already published by the CMS Collaboration. In the top quark sector, four distinct approaches to EFT have been identified, each successfully applied in several analyses. We review the pros and cons of each approach, while illustrating them with recent analyses in which they were adopted.. CMS-CR-2020-276.- Geneva : CERN, 2020 - 7 p.

 Measurements of ${\rm t\bar t+jets}$, ${\rm t\bar t+b\bar b}$ production, and ${\rm t\bar tt\bar t}$ production at CMS / Castro, Andrea (INFN, Bologna ; Bologna U.) /CMS Collaboration The most recent CMS measurements of the production of ${\rm t\bar t}$ pairs with two additional jets, or two additional b quarks, are presented. These two processes are important for several reasons: they can allow a better modeling of Monte Carlo simulations, because of the different energy scale associated to b-jets and generic jets; they are important backgrounds to other standard model processes; and they might be related to new physics.

 Performance of CMS Endcap Precision Timing Sensors / Lazarovits, Margaret (Kansas U.) /CMS Collaboration The Large Hadron Collider, a particle accelerator in Geneva, Switzerland, will enter its High Luminosity (HL) phase, whose upgrade has already started. This phase will include an increase in particle collisions, achieving instantaneous luminosities of 5 to 7 times the nominal luminosity, $1~\times~10^{34}$~cm$^{-2}$s$^{-1}$.

 Review of results on forward physics and diffraction by CMS / Baldenegro Barrera, Cristian (Kansas U.) /CMS Collaboration Results by the CMS Collaboration on forward physics, diffraction, and physics in the small-$x$ limit of quantum chromodynamics (QCD), are presented. In particular, results on azimuthal angle decorrelations between two jets in events where two outermost jets are separated by a large rapidity interval are discussed.
