Search for b hadron decays to long-lived particles in the CMS endcap muon detectors /CMS Collaboration
A search for long-lived particles originating from the decay of $\mathrm{b}$ hadrons produced by the LHC is presented. The long-lived particles interact with the CMS endcap muon system creating hadronic showers, which are used to construct clusters. [...]

Search for resonant production of pairs of dijet resonances through broad mediators in proton-proton collisions at $\sqrt{s} = 13~\mathrm{TeV}$ /CMS Collaboration
A reinterpretation of a prior narrow resonance search is performed to investigate resonant production of dijet resonance pairs via broad mediators. This analysis targets events with four resolved jets, requiring dijet invariant masses $> 0.2~\mathrm{TeV}$ and four-jet invariant masses $> 1.6~\mathrm{TeV}$. [...]

Measurements of top quark-antiquark pair production properties in association with a W boson in proton-proton collisions at a center-of-mass energy of 13 TeV are presented, using a data sample corresponding to an integrated luminosity of $138~\mathrm{fb}^{-1}$, recorded by the CMS experiment at the CERN LHC. Events are selected based on the presence of either two leptons with the same electric charge or three leptons, and multiple jets and b-tagged jets. [...]

Inclusive and differential measurements of the $\mathrm{t\bar{t}}\gamma$ cross section and the $\mathrm{t\bar{t}}\gamma / \mathrm{t\bar{t}}$ ratio in proton-proton collisions at $\sqrt{s}=13~\mathrm{TeV}$ /CMS Collaboration
Inclusive and differential measurements of the cross section of top quark pair ($\mathrm{t\bar{t}}$) production in association with a photon ($\gamma$) are performed as a function of lepton, photon, top quark, and $\mathrm{t\bar{t}}$ kinematic observables, using $138~\mathrm{fb}^{-1}$ of proton-proton collision data at $\sqrt{s}=13~\mathrm{TeV}$. Events containing two leptons, electrons or muons, and a photon in the final state are used. [...]

Search for a very low mass diphoton resonance using 2018 data /CMS Collaboration
The existence of a new spin-zero particle with a mass lower than the electroweak scale is predicted by several theoretical models, and searches for resonant production of photon pairs at the LHC are able to probe these models. We present a search for a narrow resonance produced through gluon-fusion that decays into a pair of photons in the invariant mass range between 10 and 70 GeV, using a proton-proton collision data set from the CMS experiment.

Observation of magic states of top quark pairs produced in proton-proton collisions at $\sqrt{s}=13~\mathrm{TeV}$ /CMS Collaboration
An observation of magic states of top quark-antiquark ($\mathrm{t\bar{t}}$) systems produced in proton-proton collisions at the LHC at $\sqrt{s}=13~\mathrm{TeV}$ is presented. Magic, defined here using the second stabilizer R$\mathrm{\acute e}$nyi entropy, is an important property used to characterize quantum states in quantum information science. [...]

Search for charged lepton flavor violating Z and Z' boson decays in proton-proton collisions at sqrt(s) = 13 TeV /CMS Collaboration
A search for charged lepton flavor violating decays of the Z boson is performed using data from proton-proton collisions at $\sqrt{s}=13$ TeV collected with the CMS detector at the LHC, corresponding to an integrated luminosity of 138 fb$^{-1}$. The Z $\rightarrow$ e$\mu$, Z $\rightarrow$ e$\tau$, and Z $\rightarrow\mu\tau$ decays are considered separately, where hadronic and different-flavor leptonic $\tau$ decays are used in the latter two searches.

The nuclear shape and size dependences of Fourier flow harmonics ($v_{n}$, $n = 2,3,4$) in XeXe collisions at $\sqrt{s_{{\mathrm{NN}}}} = 5.44~\mathrm{TeV}$ and PbPb collisions at $\sqrt{s_{{\mathrm{NN}}}} = 5.36~\mathrm{TeV}$ are studied using the CMS detector. For the first time, correlations between higher-power moments of two or three flow harmonics, as a function of collision centrality, are compared in XeXe and PbPb collisions. [...]
