CMS Experiment


The Compact Muon Solenoid (CMS) experiment is one of the two large multi-purpose experiments at the Large Hadron Collider (LHC). In 2013 and 2014 no new proton-proton collision data were collected, as the LHC underwent a two-year-long service break. The LHC dipole magnets were repaired so that the collision energy could be raised to 13 TeV when the LHC restarted in Summer 2015. The CMS detector underwent basic maintenance and reparations during this Long Shutdown 1. Years 2013 and 2014 were nevertheless very productive: a large number of physics analyses have been completed with the full Run 1 statistics (~5 fb-1 at 7 TeV and ~20 fb-1 at 8 TeV). The CMS collaboration submitted about 65 papers for publication in 2013. The total number of CMS publications reached 300 early in 2014 and 400 in June 2015. For real time statistics on CMS’s publications, see the CMS Physics Papers Timeline.

The HIP CMS experiment project is involved in the CMS physics analyses, concentrating in particular in B physics, Higgs searches and jet physics. The project is also contributing to the tracker alignment, jet energy corrections and leading the CMS efforts in data preservation and open access.

The HIP physics analysis team takes active part in the CMS computing, software and analysis effort. The activities range from detector and physics simulation studies in view of exploring the CMS physics performance to the reconstruction and analysis of the events. Detailed analysis of the CMS detector and it’s performance is reported in Physics Technical Design Report Volume I (31.4 MB) and the CMS physics performance in Physics Technical Design Report Volume II (25.8 MB).
