Measurement of the top-quark mass in t̄t events with lepton+jets final states in pp collisions at √s =7 TeV
The mass of the top quark is measured using a sample of t̄t candidate events with one electron or muon and at least four jets in the final state, collected by CMS in pp collisions at √s =7 TeV at the LHC. A total of 5174 ...
Search for resonant t̄t production in lepton+jets events in pp collisions at √s=7 TeV
A model-independent search for the production of heavy resonances decaying into top-antitop quark pairs is presented. The search is based on events containing one lepton (muon or electron) and at least two jets selected ...
Observation of Z decays to four leptons with the CMS detector at the LHC
The first observation of the Z boson decaying to four leptons in proton-proton collisions is presented. The analyzed data set corresponds to an integrated luminosity of 5.02 fb-1 at s=7 TeV collected by the CMS detector ...
