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 ...
Searches for long-lived charged particles in pp collisions at √s = 7 and 8 TeV
Results of searches for heavy stable charged particles produced in pp collisions at √s = 7 and 8 TeV are presented corresponding to an integrated luminosity of 5.0 fb−1 and 18.8 fb−1, respectively. Data collected 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 ...
Search for microscopic black holes in pp collisions at √s = 8 TeV
A search for microscopic black holes and string balls is presented, based on a data sample of pp collisions at √s = 8 TeV recorded by the CMS experiment at the Large Hadron Collider and corresponding to an integrated ...
