Prospects for a Search for Doubly Charged Higgs Bosons at the HL-LHC /CMS Collaboration
A variety of new physics theories, including left-right symmetric and type-II seesaw models, predict a massive, TeV-scale, doubly charged Higgs-like particle. These can be pair-produced in hadronic interactions via a Drell-Yan-like mechanism and decay to a pair of like-sign muons or electrons. [...]

Search for dark matter in final states with a Higgs boson decaying to a pair of b-jets and missing transverse momentum at the HL-LHC /CMS Collaboration
We perform a projection study for the sensitivity of the upgraded CMS detector to new physics in a mono-Higgs sector, h $\to$ bb plus missing transverse momentum final state, at the HL-LHC. The focus lies on signals with boosted Higgs bosons, resulting in a large radius jet containing both b quarks that can are identified as originating from a Higgs boson. [...]

A profile likelihood approach to measure the top quark mass in the lepton+jets channel at $\sqrt{s}=13~\mathrm{TeV}$ /CMS Collaboration
The mass of the top quark is measured in $36~\mathrm{fb}^{-1}$ of LHC proton-proton collision data collected with the CMS detector at $\sqrt{s}=13~\mathrm{TeV}$. The measurement uses a sample of $\rm{t}\bar{\rm t}$ events containing one isolated muon or electron and at least four jets in the final state. [...]

Probing hydrodynamics and the moments of the elliptic flow distribution in $\sqrt{s_{\mathrm{NN}}}=5.02~\mathrm{TeV}$ lead-lead collisions using higher-order cumulants /CMS Collaboration
The $v_{2}$ cumulant values for the elliptic anisotropy harmonic, $v_{2}\{2k\}$, are determined up to the tenth order ($k = 5$) as a function of the collision centrality in $\sqrt{s_{\mathrm{NN}}}=5.02~\mathrm{TeV}$ lead-lead collisions. The data were obtained by the CMS experiment at the LHC. [...]

Azimuthal anisotropy of nonprompt $\mathrm{D}^0$ mesons in PbPb collisions at $\sqrt{s_{_{\mathrm{NN}}}}=5.02~\mathrm{TeV}$ /CMS Collaboration
The azimuthal anisotropy elliptic ($v_2$) and triangular ($v_3$) Fourier coefficients of $\mathrm{D}^0$ mesons produced in B hadron decays are measured in PbPb collisions at $\sqrt{s_{_{\mathrm{NN}}}}=5.02~\mathrm{TeV}$. Due to the larger bottom quark mass as compared to the charm quark mass, separate measurements of charm and bottom hadron azimuthal anisotropy can shed new light on understanding the mass dependence of the heavy quark and medium interaction.

Azimuthal anisotropy of $\Upsilon\textrm{(1S)}$ mesons in pPb collisions at $\sqrt{\mathrm{s_{NN}}} = 8.16 ~\mathrm{TeV}$ /CMS Collaboration
The azimuthal anisotropy of $\Upsilon\textrm{(1S)}$ mesons in high-multiplicity proton-lead (pPb) collisions is studied using data collected by the CMS experiment at a center-of-mass energy per nucleon pair of $\sqrt{\mathrm{s_{NN}}} = 8.16 ~\mathrm{TeV}$. The $\Upsilon\textrm{(1S)}$ mesons are reconstructed from the dimuon decay channel. [...]

Measurement of two-particle Bose-Einstein momentum correlations and their Levy parameters at $\sqrt{s_{_{\mathrm{NN}}}}=5.02$ TeV PbPb collisions /CMS Collaboration
Charged hadron, two-particle Bose-Einstein momentum correlation functions in lead-lead (PbPb) collisions at an average center of mass energy per nucleon ($\sqrt{s_{_{\mathrm{NN}}}}$) of 5.02 TeV are presented. The data were obtained in 2018 by the CMS experiment at the LHC. [...]

Correlations between multiparticle cumulants and mean transverse momentum in small collision systems with the CMS detector /CMS Collaboration
Correlations between multiparticle cumulants and mean transverse momentum in proton-proton (pp), proton-lead (pPb) and peripheral lead-lead (PbPb) collisions are presented as a function of charged-particle multiplicity. The data, corresponding to integrated luminosities of $28.6~\mathrm{pb}^{-1}$ for pp at $\sqrt{s}=13~\mathrm{TeV}$, $186~\mathrm{nb}^{-1}$ for pPb at $\sqrt{s_{_{\mathrm{NN}}}}=8.16~\mathrm{TeV}$, and $0.58~\mathrm{nb}^{-1}$ for PbPb at $\sqrt{s_{_{\mathrm{NN}}}}=5.02~\mathrm{TeV}$, were collected using the CMS detector at the LHC.

Observation of the $\Upsilon\textrm{(3S)}$ meson and sequential suppression of $\Upsilon$ states in PbPb collisions at $\sqrt{\mathrm{s_{NN}}}=5.02~\mathrm{TeV}$ /CMS Collaboration
The production of $\Upsilon\textrm{(2S)}$ and $\Upsilon\textrm{(3S)}$ mesons in lead-lead (PbPb) and proton-proton (pp) collisions is studied using the CMS detector at the LHC. Their nuclear modification factors, $R_{\textrm{AA}}$, derived from the ratio of yields measured in PbPb to pp collisions, are reported as functions of transverse momentum and PbPb collision centrality.
