Search for the rare decays of the Z and Higgs bosons to a $\mathrm{J}/\Psi$ or $\Psi^{\prime}$ meson and a photon in proton-proton collisions at $\sqrt{s}=13~\mathrm{TeV}$ /CMS Collaboration
A search is performed for the rare decays of the Z and Higgs bosons to a photon and a charmed meson $\mathrm{J}/\Psi$ or $\Psi^{\prime}$, which subsequentially decays to a pair of muons. The data set corresponds to an integrated luminosity of $123~\mathrm{fb}^{-1}$ of proton-proton collisions at $\sqrt{s}=13~\mathrm{TeV}$ collected with the CMS detector at the LHC. [...]

Constraints on the Higgs boson self-coupling with combination of single and double Higgs boson production /CMS Collaboration
A combination of Higgs boson (H) measurements and searches for the production of Higgs boson pairs (HH) is presented, aiming to constrain the H trilinear self-coupling $\lambda_3$, using the proton-proton collision data collected by the CMS experiment at $\sqrt{s} = 13~\mathrm{TeV}$. The cross section of the main H production modes and the branching ratios of the principal decay channels depend on $\lambda_3$ because of next-to-leading-order electroweak corrections. [...]

Measurement of the Higgs boson mass and width using the four leptons final state /CMS Collaboration
A measurement of the Higgs boson mass and width using the decays to two Z bosons is presented, using the proton-proton data collected by the CMS experiment at the LHC corresponding to an integrated luminosity of $138~\mathrm{fb}^{-1}$ at a center-of-mass energy of $13~\mathrm{TeV}$. The on-shell production of the Higgs boson with the decay $\mathrm{H} \to \mathrm{Z} \mathrm{Z}^* \to 4\ell$ is used to constrain its mass and width, which yields to the most precise single measurement of the mass to date $\mathrm{m}_\mathrm{H} = 125.08 \pm 0.12~\mathrm{GeV}$ and an upper limit on the width $\Gamma_\mathrm{H} < 60~\mathrm{MeV}$ at $68\%$ confidence level.
