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.

Study of semileptonic vector boson scattering and anomalous quartic gauge coupling from proton-proton collisions at 13 TeV /CMS Collaboration
A measurement of the electroweak production of ZV (V = W, Z) boson pairs associated with two jets in proton-proton collisions at a center-of-mass energy of 13 TeV is presented. The analysis targets final states with two isolated electrons or muons from Z decays and three to four jets, depending on the momentum of the vector boson that decays into quarks. [...]

Characterizing the Initial State in XeXe and PbPb Collisions using Multiparticle Cumulants /CMS Collaboration
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. [...]

First $k_{\mathrm{T}}$ scan of the Lund jet plane in heavy-ion collisions to test the factorization of the vacuum and medium parton shower /CMS Collaboration
This note presents the first relative transverse momentum ($k_{\mathrm{T}}$) scan of the Lund jet plane for high-energy jets in lead-lead (Pb-Pb) collisions at the LHC at a nucleon-nucleon center-of-mass energy of 5.02 TeV. We report the fully corrected angular distribution of the primary emissions with the highest $k_{\mathrm{T}}$ in two different ranges of $k_{\mathrm{T}}$ for anti-$k_{\mathrm{T}}$ jets with distance parameter $R=0.4$ and transverse momentum in the range $200 < p_{\mathrm{T}}^\text{jet} < 1000$ GeV.
