An overview of physics results from the CMS experiment at the LHC is given. The present analysis is based on data obtained for colliding proton beams at the c.m. energies of and 13 TeV over the period of LHC Run-1 and Run-2.
New unique data on interactions of Standard Model particles at record energies were obtained in the course of the first run of LHC operation. The Higgs boson was discovered, and investigation of its properties was initiated. Measurements were performed for Standard Model processes, including rare and one previously unobserved. This allowed one to refine some parameters of the Standard Model and set limits on the parameters of some theoretical models beyond the Standard Model, for example, on the masses of new particles, the fundamental energy scales, the coupling constants, and the cross sections for the new particles production.
