Search for heavy pseudoscalar and scalar bosons decaying to top quark pairs in proton-proton collisions at /CMS Collaboration
A search for heavy pseudoscalar or scalar bosons decaying to a top quark pair ($\mathrm{t\bar{t}}$) in final states with one or two charged leptons is presented, using $138\,\mathrm{fb}^{-1}$ of proton-proton collisions at $\sqrt{s}=13\,\mathrm{TeV}$ recorded by the CMS experiment at the CERN LHC. The invariant mass of the reconstructed $\mathrm{t\bar{t}}$ system and variables sensitive to its spin state are used to discriminate against the standard model $\mathrm{t\bar{t}}$ background. [...]

Combined effective field theory interpretation of Higgs boson, electroweak vector boson, top quark, and multi-jet measurements /CMS Collaboration
Constraints on the Wilson coefficients (WCs) corresponding to dimension-six operators of the standard model effective field theory (SMEFT) are determined from a simultaneous fit to seven sets of CMS measurements probing Higgs boson, electroweak vector boson, top quark, and multi-jet production. The measurements of the electroweak precision observables at LEP and SLC are also included and provide complementary constraints to those from CMS. [...]

Wasserstein normalized autoencoder /CMS Collaboration
A novel approach to unsupervised jet tagging is presented for the CMS experiment at the CERN LHC. The Wasserstein normalized autoencoder (WNAE) is a normalized probabilistic model that minimizes the Wasserstein distance between the probability distribution of the training data and the Boltzmann distribution of the reconstruction error of the autoencoder.
