The results of a search for a standard model-like Higgs boson decaying into two photons in the mass range between 70 and 110 GeV are presented. The analysis uses the data set collected by the CMS experiment in proton-proton collisions at s …

A search is presented for heavy bosons decaying to $Z(\ensuremath{\nu}\overline{\ensuremath{\nu}})V(q{\overline{q}}^{\ensuremath{'}})$, where $V$ can be a $W$ or a $Z$ boson. A sample of proton-proton collision data at $\sqrt{s}=13\text{ }\text{ }\mathrm{TeV}$ was collected by the CMS experiment during 2016--2018. The data correspond to …

Abstract A direct search for electroweak production of charginos and neutralinos is presented. Events with three or four leptons, with up to two hadronically decaying τ leptons, or two same-sign light leptons are analyzed. The data sample consists of 137 fb−1 of …

A search is presented for long-lived particles produced in pairs in proton-proton collisions at the LHC operating at a center-of-mass energy of $13\text{ }\text{ }\mathrm{TeV}$. The data were collected with the CMS detector during the period from 2015 through 2018, and correspond …

The polarizations of promptly produced ${\ensuremath{\chi}}_{c1}$ and ${\ensuremath{\chi}}_{c2}$ mesons are studied using data collected by the CMS experiment at the LHC, in proton-proton collisions at $\sqrt{s}=8\text{ }\text{ }\mathrm{TeV}$. The ${\ensuremath{\chi}}_{c}$ states are reconstructed via their radiative decays ${\ensuremath{\chi}}_{c}\ensuremath{\rightarrow}J/\ensuremath{\psi}\ensuremath{\gamma}$, with the photons being …
