TL;DR: The top quark charge asymmetry is measured in highly Lorentz-boosted top quark pair events at 13TeV proton-proton collisions, yielding a 0.42-0.69+0.64% result in agreement with the standard model prediction, with corrections for detector and acceptance effects.

TL;DR: Measurement of electroweak W$\gamma$ production in association with two jets in proton-proton collisions at 13 TeV. The cross section and differential cross sections are measured and are in agreement with the standard model expectations. Constraints on anomalous quartic gauge couplings are also presented.

TL;DR: In this paper , a search for pairs of light Higgs bosons produced in supersymmetric cascade decays in final states with small missing transverse momentum is reported, and results from the search are interpreted in the next-to-minimal superymmetric extension of the SM, where a “singlino” of small mass leads to squark and gluino cascades that can predominantly end in a highly Lorentz-boosted singlet-like boson.

TL;DR: Measurements of azimuthal anisotropy (v2 and v3) of prompt and nonprompt charmonia (J/ψ and ψ(2S)) in PbPb collisions at √sNN = 5.02 TeV reveal differences in v2 values between prompt and nonprompt J/ψ mesons, challenging parton energy loss models.

TL;DR: In this article , the branching fraction ratios of 13 TeV proton-proton collisions collected by the CMS experiment at the LHC in 2017 and 2018 with an integrated luminosity of 103 fb$^{-1} were measured for the first time.
