Abstract
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 $\rad{}{s} = 8$ 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.
Highlights
This report covers recent physics results from CMS [1] including precision measurements of the Higgs boson, first observed by the ATLAS and CMS collaborations in 2012 [2],[3] and top quark properties, b-physics, and Standard Model (SM) phenomena; searches for new particles
CMS has continued its prolific production of physics results
Higgs decay to τ+τ−: The decay of the Higgs into τ+τ− is reconstructed in four separate decay modes, eμ, eτh, μτh, and τhτh and in three production channels, 0-jet, Vector Boson Fusion (VBF), and “boosted" one [6]
Summary
This report covers recent physics results from CMS [1] including precision measurements of the Higgs boson, first observed by the ATLAS and CMS collaborations in 2012 [2],[3] and top quark properties, b-physics, and Standard Model (SM) phenomena; searches for new particles. It will conclude with a summary and outlook. In anticipation of a high peak and integrated luminosity in 2016 and beyond, CMS made various improvements and upgrades to the detector These included the improved Level 1 Muon Trigger and Calorimeter Triggers. Two of them are Particle Flow (PF) [4] and Pile UP per Proton Interaction (PUPPI) [5]
