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 ...
Azimuthal anisotropy of charged particles at high transverse momenta in Pb-Pb collisions at √s NN=2.76TeV
(American Physical Society, 2012-07)
The azimuthal anisotropy of charged particles in Pb-Pb collisions at √sNN=2.76 TeV is measured with the CMS detector at the LHC over an extended transverse momentum (pT) range up to approximately 60 GeV/c. The data cover ...
Inclusive search for squarks and gluinos in pp collisions at √s=7 TeV
(American Physical Society, 2012-01)
A search is performed for heavy particle pairs produced in √s=7 TeV proton-proton collisions with 35 pb[superscript -1] of data collected by the CMS experiment at the LHC. The search is sensitive to squarks and gluinos ...
Measurement of the top-quark mass in t[overline t] events with lepton+jets final states in pp collisions at √s = 7 TeV
(Springer Nature, 2012-12)
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 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 ...
Search for new physics in events with opposite-sign leptons, jets, and missing transverse energy in pp collisions at √s = 7 TeV
(Elsevier, 2012-11)
A search is presented for physics beyond the standard model (BSM) in final states with a pair of opposite-sign isolated leptons accompanied by jets and missing transverse energy. The search uses LHC data recorded at a ...
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 ...
A search for a doubly-charged Higgs boson in pp collisions at s√=7 TeV
(Springer-Verlag, 2012-11)
A search for a doubly-charged Higgs boson in pp collisions at s√=7 TeVs is presented. The data correspond to an integrated luminosity of 4.9 fb[superscript −1], collected by the CMS experiment at the LHC. The search is ...
Search for the Standard Model Higgs Boson in the Decay Channel H→ZZ→4l in pp Collisions at √s=7 TeV
(American Physical Society, 2012-03)
A search for a Higgs boson in the four-lepton decay channel H→ZZ, with each Z boson decaying to an electron or muon pair, is reported. The search covers Higgs boson mass hypotheses in the range of 110<m[subscript H]<600 GeV. ...
Search for flavor changing neutral currents in top quark decays in pp collisions at 7 TeV
(Elsevier, 2012-12)
The results of a search for flavor changing neutral currents in top quark decays t→Zq in events with a topology compatible with the decay chain tt¯→Wb+Zq→ℓνb+ℓℓq are presented. The search is performed with a data sample ...
