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

TL;DR

The CMS experiment at the LHC collected high-quality proton-proton collision data in 2010, successfully calibrating the detector and demonstrating capabilities for Standard Model measurements and new physics searches surpassing previous colliders.

Contribution

First results from the 2010 LHC run showing detector performance, Standard Model process measurements, and initial searches for new physics.

Findings

Detector calibration close to design specifications

Reestablished Standard Model processes

Enhanced sensitivity for new physics searches

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.
