Searches for New Physics in the Dilepton Channel with the CMS Detector at the Large Hadron Collider

Results of searches for signals from new physics beyond the Standard Model in proton–proton collisions at the c.m. energy of $\sqrt{s}=13$ TeV are surveyed. Dilepton-production events detected by the CMS experiment during Run 2 of the Large Hadron Collider (LHC) are used in these searches. The total amount of the data under analysis corresponds to an integrated luminosity of up to 140 fb${}^{-1}$. The results in question were interpreted within models of an extended gauge sector, scenarios of low-energy gravity, and in the context of searches for dark-matter particles. The results of searches for the rare Higgs boson decay to two muons are also discussed.
