Search for anomalous production of multilepton events in pp collisions at √s = 7 TeV
Abstract: A search for anomalous production of events with three or more isolated leptons in pp collisions at √s = 7 TeV is presented. The data, corresponding to an integrated luminosity of 4.98 fb−1, were collected by ...
Exclusive γγ → +μμ - production in proton-proton collisions at √s = 7 TeV
A measurement of the exclusive two-photon production of muon pairs in proton-proton collisions at √s = 7 TeV, pp → pμ+μ−p, is reported using data corresponding to an integrated luminosity of 40 pb−1. For muon pairs with ...
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 ...
Study of the underlying event at forward rapidity in pp collisions at √s = 0.9, 2.76, and 7 TeV
The underlying event activity in proton-proton collisions at forward pseudo-rapidity (−6.6 < η < −5.2) is studied with the CMS detector at the LHC, using a novel observable: the ratio of the forward energy density, dE/dη, ...
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 tt¯ 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 ...
