First results from the 2010 pp Run and performance of the CMS Experiment

Abstract

In 2010, the Compact Muon Solenoid (CMS) experiment at LHC recorded over 45 pb^-1 of pp collision data at sqrt(s)=7 TeV. The large collected datasets are of very high quality and have been used to commission and calibrate the CMS detector, with the achieved performance close to the TDR specifications. CMS has reestablished all the major Standard Model processes in the 2010 Run and is entering new territory in searches for New Physics, with sensitivity already exceeding that at LEP and TeVatron.
