Measurement of R($J/\psi$) in the hadronic tau decay channel /CMS Collaboration
A measurement of the ratio of branching fractions $\mathcal{R}_{\text{J}/\psi} = \mathcal{B}(\text{B}_\text{c}^{+}\to\text{J}/\psi\tau^{+}\nu_\tau) / \mathcal{B}(\text{B}_\text{c}^{+}\to\text{J}/\psi\mu^{+}\nu_\mu)$ in the decay channel with $\text{J}/\psi(\rightarrow\mu^{+}\mu^{-})$ and $\tau^{+}\rightarrow\pi^{+}\pi^{-}\pi^{+}(+\pi^{0})\bar{\nu}_{\tau}$ (and charge-conjugated processes) is presented. This measurement uses a sample of proton-proton collision data, corresponding to an integrated luminosity of $138\,\mathrm{fb}^{-1}$, collected at a center-of-mass energy of $13\,\mathrm{TeV}$ by the CMS experiment in the LHC Run 2.

Phenomenological MSSM interpretation of CMS searches in pp collisions at 13 TeV /CMS Collaboration
A number of searches for new physics performed by the CMS experiment during years 2016-2018 of the CERN LHC data taking are interpreted in terms of a 19-parameter scan of the phenomenological minimal supersymmetric standard model (pMSSM). The data sets are of proton-proton collisions collected at $\sqrt{s}=13~\mathrm{TeV}$ and correspond to an integrated luminosity of $138~\mathrm{fb}^{-1}$. [...]

Energy-energy correlators from PbPb and pp collisions at 5.02 TeV /CMS Collaboration
Energy-energy correlators have recently gained prominence as experimental observables that have predicted sensitivities to a multitude of perturbative and non-perturbative quantum chromodynamics phenomena in high-energy collisions. Using data recorded by the CMS detector, energy-energy correlators are measured in lead-lead (PbPb) collisions for the first time. [...]

Measurement of the dineutrino system kinematics in dileptonic top quark pair events in pp collisions at \texorpdfstring{$\sqrt{s} = 13\,$}TeV /CMS Collaboration
Differential top quark pair cross sections are measured in the dilepton final states $e^{+}e^{-}$, $\mu^{+}\mu^{-}$, and $e^{\pm}\mu^{\mp}$, as a function of kinematics of the system of two neutrinos: the transverse momentum $p_{T}^{\nu\nu}$ of the dineutrino system, the minimum distance in azimuthal angle between $p_{T}^{\nu\nu}$ and leptons, and in two dimensions in bins of both observables. The measurements are performed using CERN LHC proton-proton collisions at $\sqrt{s} = 13\,$TeV, recorded by the CMS detector between 2016 and 2018, corresponding to an integrated luminosity of 138 fb$^{-1}$.
