Search for new physics with long-lived particles decaying to photons and missing energy in pp collisions at √s = 7 TeV
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 supersymmetry with razor variables in pp collisions at s =7TeV
The razor approach to search for R-parity conserving supersymmetric particles is described in detail. Two analyses are considered: an inclusive search for new heavy particle pairs decaying to final states with at least two ...
Search for stopped long-lived particles produced in pp collisions at √s = 7 TeV
A search has been performed for long-lived particles that have stopped in the CMS detector, during 7 TeV proton-proton operations of the CERN LHC. The existence of such particles could be inferred from observation of their ...
Search for anomalous production of events with three or more leptons in pp collisions at s =8TeV
A search for physics beyond the standard model in events with at least three leptons is presented. The data sample, corresponding to an integrated luminosity of 19.5fb-1 of proton-proton collisions with center-of-mass ...
Search for W′→tb decays in the lepton + jets final state in pp collisions at √s = 8 TeV
Results are presented from a search for the production of a heavy gauge boson W′ decaying into a top and a bottom quark, using a data set collected by the CMS experiment at √s = 8 TeV and corresponding to an integrated ...
Determination of the top-quark pole mass and strong coupling constant from the tt̄ production cross section in pp collisions at √s = 7 TeV
The inclusive cross section for top-quark pair production measured by the CMS experiment in proton-proton collisions at a center-of-mass energy of 7 TeV is compared to the QCD prediction at next-to-next-to-leading order ...
Search for quark compositeness in dijet angular distributions from pp collisions at √s = 7 TeV
A search for quark compositeness using dijet angular distributions from pp collisions at √s = 7 TeV is presented. The search has been carried out using a data sample corresponding to an integrated luminosity of 2.2 fb−1, ...
Erratum to: Search for new physics in events with same-sign dileptons and jets in pp collisions at √s = 8 TeV
Erratum to: JHEP01(2014)163. The online version of the original article can be found at http://dx.doi.org/10.1007/JHEP01(2014)16
Search for anomalous tt̄ production in the highly-boosted all-hadronic final stat
A search is presented for a massive particle, generically referred to as a Z′, decaying into a tt¯ pair. The search focuses on Z′ resonances that are sufficiently massive to produce highly Lorentz-boosted top quarks, which ...
Search for new physics in the multijet and missing transverse momentum final state in proton-proton collisions at √s = 8 TeV
A search for new physics is performed in multijet events with large missing transverse momentum produced in proton-proton collisions at √s = 8 TeV using a data sample corresponding to an integrated luminosity of 19.5 fb−1 ...
