CERN-LHC. The normalised differential top quark-antiquark production cross section is measured as a function of the jet multiplicity in proton-proton collisions at a centre-of-mass energy of 7 TeV at the LHC with the CMS detector. The measurement is performed in both the …

A search is presented for long-lived charged particles that decay within the CMS detector and produce the signature of a disappearing track. Disappearing tracks are identified as those with little or no associated calorimeter energy deposits and with missing hits in the …

Abstract The first measurement of the electroweak production cross section of a Z boson with two jets (Zjj) in pp collisions at $ \sqrt{s}=7 $ TeV is presented, based on a data sample recorded by the CMS experiment at the LHC with …

A search for physics beyond the standard model is performed with events having one or more hadronically decaying τ leptons, highly energetic jets, and large transverse momentum imbalance.The data sample corresponds to an integrated luminosity of 4.98 fb -1 of proton-proton collisions …

A search is presented for charge-asymmetric production of a W boson that has been proposed to accommodate the forward-backward asymmetry observed in the production of top-antitop quark pairs at the Tevatron.The new heavy W boson would be produced in association with a …
