Study of the Dijet Mass Spectrum in pp→W+jets Events at √s=7 TeV
(American Physical Society, 2012-12)
We report an investigation of the invariant mass spectrum of the two jets with highest transverse momentum in pp→W+2-jet and W+3-jet events to look for resonant enhancement. The data sample corresponds to an integrated ...
Search for the standard model Higgs boson decaying into two photons in pp collisions at √s = 7 TeV
(Elsevier B.V., 2012-04)
A search for a Higgs boson decaying into two photons is described. The analysis is performed using a dataset recorded by the CMS experiment at the LHC from pp collisions at a center-of-mass energy of 7 TeV, which corresponds ...
Measurement of the t[bar over t] production cross section in the dilepton channel in pp collisions at √s =7 TeV
(Springer Nature, 2012-11)
The t[bar over t] over bar production cross section (σ[subscript t[bar pver t]) over bar)) is measured in proton-proton collisions at root √s = 7 TeV in data collected by the CMS experiment, corresponding to an integrated ...
Search for new physics with long-lived particles decaying to photons and missing energy in pp collisions at √s=7 TeV
(Springer Science and Business Media LLC, 2012)
A search is performed for long-lived neutral particles decaying into a photon and invisible particles. An example of such a signature is the decay of the lightest neutralino with nonzero lifetime into a gravitino and a ...
Performance of τ-lepton reconstruction and identification in CMS
(IOP Publishing, 2012-01-01)
The performance of τ-lepton reconstruction and identification algorithms is studied using a data sample of proton-proton collisions at s = 7 TeV, corresponding to an integrated luminosity of 36 pb-1 collected with the CMS ...
Measurement of the relative prompt production rate of χ[subscript c2] and χ[subscript c1] in pp collisions at √s = 7TeV
(Springer-Verlag, 2012-11)
A measurement is presented of the relative prompt production rate of χ[subscript c2] and χ[subscript c1] with 4.6 fb[superscript −1] of data collected by the CMS experiment at the LHC in pp collisions at √s = 7 TeV. The ...
Measurement of the top-quark mass in t[bar over t] events with dilepton final states in pp collisions at s√=7 TeV
(Springer-Verlag, 2012-10)
The top-quark mass is measured in proton-proton collisions at s√=7 TeV using a data sample corresponding to an integrated luminosity of 5.0 fb[superscript −1] collected by the CMS experiment at the LHC. The measurement is ...
Search for new physics in events with same-sign dileptons and b-tagged jets in pp collisions at √s = 7 TeV
(Springer-Verlag, 2012-08)
A search for new physics is performed using isolated same-sign dileptons with at least two b-quark jets in the final state. Results are based on a 4.98 fb[superscript −1] sample of proton-proton collisions at a centre-of-mass ...
Exclusive γγ → μ⁺μ⁻ production in proton-proton collisions at √s = 7 TeV
(Springer Berlin Heidelberg, 2012-01)
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 ...
Measurement of the single-top-quark t-channel cross section in pp collisions at √s = 7 TeV
(Springer Nature, 2012-12)
A measurement of the single-top-quark t-channel production cross section in pp collisions at √s=7 TeV with the CMS detector at the LHC is presented. Two different and complementary approaches have been followed. The first ...
