Combination of the ATLAS, CMS and LHCb results on the $B^0_{(s)} \to \mu^+\mu^-$ decays
/CMS Collaboration ; LHCb Collaboration ; ATLAS Collaboration
A combination of results on the rare $B^0_s \to \mu^+\mu^-$ and $B^0 \to \mu^+\mu^-$ decays from the ATLAS, CMS, and LHCb experiments using data collected at the Large Hadron Collider between 2011 and 2016, is presented. The $B^0_s \to \mu^+\mu^-$ branching fraction is obtained to be $(2.69\,^{+\, 0.37}_{-\, 0.35}) \times 10^{-9}$ and the effective lifetime of the $B^0_s \to \mu^+\mu^-$ decay is measured to be $\tau_{B^0_s \to \mu^+\mu^-} = 1.91^{+0.37}_{-0.35}$ ps.

Search for a spin-1 heavy resonance that decays to a Z boson and Higgs boson in the semileptonic final states with Run-2 data
/CMS Collaboration
This note describes the search for a heavy spin-1 resonance decaying into a Z boson and the 125-GeV Higgs boson, where the Z boson is identified through its leptonic decays (electrons, muons or neutrinos) and the Higgs boson is identified through its decay to quarks. The search is performed in the boosted regime for resonances with masses larger than 800 GeV. [...]

Study of in-medium modification of dijets in PbPb collisions at 5.02 TeV
/CMS Collaboration
Modifications to the distribution of charged particles with respect to high transverse momentum $(p_{\mathrm{T}})$ jets passing through a quark-gluon plasma are explored. Jets corresponding to dijet selection where the leading and subleading jets are back-to-back are studied in lead-lead (PbPb) and proton-proton (pp) collisions. [...]

Measurements of Higgs boson production in the channel where the Higgs boson decays to $\tau$ leptons are performed. The analysis uses events recorded in proton-proton collisions by the CMS experiment at the CERN LHC in 2016, 2017, and 2018 at a center-of-mass energy of $13~\mathrm{TeV}$. [...]

Constraints on anomalous Higgs boson couplings to vector bosons and fermions in production and decay in the $H\to4\ell$ channel
/CMS Collaboration
Studies of CP-violation and anomalous couplings of the Higgs boson to vector bosons and fermions are presented. Kinematics of the Higgs boson's four-lepton decay and of its production in association with a vector boson, hadronic jets, or a top-quark pair are used. [...]

The rate for Higgs ($\mathrm{H}$) bosons production in association with either one ($\mathrm{t}\mathrm{H}$) or two ($\mathrm{t}\bar{\mathrm{t}}\mathrm{H}$) top quarks is measured in final states with multiple electrons, muons, and hadronically decaying $\tau$ leptons, using proton-proton collision data recorded at a center-of-mass energy of $13~\mathrm{TeV}$ by the CMS experiment. The analyzed data set corresponds to an integrated luminosity of $137~\mathrm{fb}^{-1}$. [...]

Angular analysis of the decay ${\mathrm B^{+} \to \mathrm K^{*+} \mu^{+} \mu^{-}}$ in proton-proton collisions at $\sqrt{s}=8~\mathrm{TeV}$
/CMS Collaboration
Angular distributions of the decay ${\mathrm B^{+} \to \mathrm K^{*+} \mu^{+} \mu^{-}}$ are studied using events collected with the CMS detector from $\sqrt{s}=8~\mathrm{TeV}$ proton-proton collisions, corresponding to an integrated luminosity of $20.0~\mathrm{fb}^{-1}$. The forward-backward asymmetry of the muons and the longitudinal polarization of the $\mathrm K^{*+}$ meson are determined for an integrated sample and as a function of the dimuon invariant mass squared.
