Latest results of the CMS experiment

Abstract

The Compact Muon Solenoid (CMS) experiment at CERNs Large Hadron Collider (LHC) has started to collect and analyze proton-proton collisions at ps √s= 7 TeV. At the time of this conference, CMS had collected ≈ 300 nb-1 of collision data, including small samples at lower energies of 0.9 TeV and 2.36 TeV. These samples allowed some precise studies of QCD and heavy flavour physics, the first cross section measurements of the W and Z bosons at 7 TeV, the first hints of reobservation of the top quark, and even the start of the exploration of the allowed parameter space of some new physics models. The results presented here demonstrate good detector performance and illustrate well understood physics signatures that may lead in the near future to discovery physics at the LHC. © 2010 IOP Publishing Ltd.
