Search for microscopic black holes in pp collisions at √s=8 TeV
(Springer Berlin Heidelberg, 2013-07)
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 ...
Measurement of differential top-quark-pair production cross sections in pp collisions at √s = 7TeV
Search for heavy quarks decaying into a top quark and a W or Z boson using lepton + jets events in pp collisions at s√=7TeV
Results are presented from a search for the pair-production of heavy quarks, QQ[overline appears over second Q], that decay exclusively into a top quark and a W or Z boson. The search is performed using a sample of ...
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 the ...
Study of the underlying event at forward rapidity in pp collisions at √s=0.9,2.76, and 7 TeV
(Springer Science and Business Media LLC, 2013)
© 2013, CERN. 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 ...
Search for physics beyond the standard model in events with τ leptons, jets, and large transverse momentum imbalance in pp collisions at √s=7 TeV
A search for physics beyond the standard model is performed with events having one or more hadronically decaying τ leptons, highly energetic jets, and large transverse momentum imbalance. The data sample corresponds to an ...
Search for top-squark pair production in the single-lepton final state in pp collisions at √s = 8 TeV
This paper presents a search for the pair production of top squarks in events with a single isolated electron or muon, jets, large missing transverse momentum, and large transverse mass. The data sample corresponds to an ...
Search for flavor changing neutral currents in top quark decays in pp collisions at 7 TeV
(Elsevier BV, 2013)
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 tt̄→Wb+Zq→ℓνb+ℓℓq are presented. The search is performed with a data sample ...
Search for gluino mediated bottom- and top-squark production in multijet final states in pp collisions at 8 TeV
(Elsevier BV, 2013-07)
A search for supersymmetry is presented based on events with large missing transverse energy, no isolated electron or muon, and at least three jets with one or more identified as a bottom-quark jet. A simultaneous examination ...
Jet and underlying event properties as a function of charged-particle multiplicity in proton–proton collisions at √s= 7 TeV
Characteristics of multi-particle production in proton-proton collisions at √s = 7 TeV are studied as a function of the charged-particle multiplicity, N ch . The produced particles are separated into two classes: those ...
