A measurement of the W boson mass in proton-proton collisions at sqrts = 13 TeV /CMS Collaboration
In the standard model of particle physics, the masses of the carriers of the weak interaction, the W and Z bosons, are uniquely related. Physics beyond the standard model can change this relationship through the effects of virtual particle quantum loops, thus making it of paramount importance to measure these masses with the highest possible precision.

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).

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$^{-1}$.
