Search for supersymmetry in pp collisions at root s=8 TeV in events with a single lepton, large jet multiplicity, and multiple b jets
(Elsevier, 2014)
Results are reported from a search for supersymmetry in pp collisions at a center-of-mass energy of 8 TeV, based on events with a single isolated lepton (electron or muon) and multiple jets, at least two of which are ...
Search for anomalous production of events with three or more leptons in pp collisions at root s=8 TeV
(American Physical Society, 2014-08-01)
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 19.5 fb−1 of proton-proton collisions with center-of-mass ...
Measurement of the azimuthal anisotropy of neutral pions in Pb-Pb collisions at root S-NN=2.76 TeV
(American Physical Society, 2013-01-25)
irst measurements of the azimuthal anisotropy of neutral pions produced in Pb-Pb collisions at a center-of-mass energy of root S-NN = 2.76 TeV are presented. The amplitudes of the second Fourier component (upsilon(2)) of ...
Measurement of the t(t)over-bar production cross section in the tau plus jets channel in pp collisions at root s=7 TeV
(Springer Science+Business Media, 2013-04)
The top-quark pair production cross section in 7 TeV center-of-mass energy proton-proton collisions is measured using data collected by the CMS detector at the LHC. The measurement uses events with one jet identified as a ...
Measurement of the ratio of the production cross sections times branching fractions of B c ± → J/ψπ ± and B± → J/ψK ± and B(B±c→J/ψπ±π±π∓)/B(B±c→J/ψπ±)B(Bc±→J/ψπ±π±π∓)/B(Bc±→J/ψπ±) in pp collisions at s√=7s=7 TeV
(Springer Science+Business Media, 2015-01)
The ratio of the production cross sections times branching fractions (σ(B±c)B(B±c→J/ψπ±))/(σ(B±)B(B±→J/ψK±))(σ(Bc±)B(Bc±→J/ψπ±))/(σ(B±)B(B±→J/ψK±)) is studied in proton-proton collisions at a center-of-mass energy of 7 ...
Measurement of the W-boson helicity in top-quark decays from t(t)over-bar production in lepton plus jets events in pp collisions at root s=7 TeV
(Springer Science+Business Media, 2013-10)
The W-boson helicity fractions in top-quark decays are measured with TeX events in the lepton+jets final state, using proton-proton collisions at a centre-of-mass energy of 7 TeV, collected in 2011 with the CMS detector ...
Measurement of differential top-quark-pair production cross sections in pp collisions at root s=7 TeV
(Springer Science+Business Media, 2013-03)
Normalised differential top-quark-pair production cross sections are measured in pp collisions at a centre-of-mass energy of 7 TeV at the LHC with the CMS detector using data recorded in 2011 corresponding to an integrated ...
Search for heavy Majorana neutrinos in μ±μ±+jets and e±e±+jets events in pp collisions at =7 TeV
(Elsevier, 2012-10-22)
A search is performed for heavy Majorana neutrinos (N) using an event signature defined by two same-sign charged leptons of the same flavour and two jets. The data correspond to an integrated luminosity of 4.98 fb−1 of pp ...
Search for pair-produced dijet resonances in four-jet final states in pp collisions at root s=7 TeV
(American Physical Society, 2013-04-05)
A search for the pair production of a heavy, narrow resonance decaying into two jets has been performed using events collected in root s = 7 TeV pp collisions with the CMS detector at the LHC. The data sample corresponds ...
Search for heavy lepton partners of neutrinos in proton-proton collisions in the context of the type III seesaw mechanism
(Elsevier, 2012-12-05)
A search is presented in proton-proton collisions at root s = 7 TeV for fermionic triplet states expected in type Ill seesaw models. The search is performed using final states with three isolated charged leptons and an ...
