Search for long-lived particles decaying to jets with displaced vertices /CMS Collaboration
We report the results of a search for long-lived particles produced in pairs in proton-proton collisions at the LHC operating at a center-of-mass energy of $\sqrt{s}=13~\mathrm{TeV}$. The data were collected by the CMS detector during the full Run 2 data taking period from 2015 through 2018, corresponding to a total integrated luminosity of $140~\mathrm{fb}^{-1}$. [...]

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. [...]
