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 ...
Measurement of the top quark mass using charged particles in pp collisions at s =8 TeV
(American Physical Society, 2016-05-01)
A novel technique for measuring the mass of the top quark that uses only the kinematic properties of its charged decay products is presented. Top quark pair events with final states with one or two charged leptons and ...
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 ...
Performance of the CMS missing transverse momentum reconstruction in pp data at root s=8 TeV
(IOP Publishing, 2015-02)
The performance of missing transverse energy reconstruction algorithms is presented using √s=8 TeV proton-proton (pp) data collected with the CMS detector. Events with anomalous missing transverse energy are studied, and ...
Search for long-lived neutral particles decaying to quark-antiquark pairs in proton-proton collisions at root s=8 TeV
(American Physical Society, 2015-01-01)
A search is performed for long-lived massive neutral particles decaying to quark-antiquark pairs. The experimental signature is a distinctive topology of a pair of jets, originating at a secondary vertex. Events were ...
Measurement of the t t ¯ production cross section in the eμ channel in proton-proton collisions at √s = 7 and 8 TeV
(Springer Nature, 2016-08)
The inclusive cross section for top quark pair production is measured in proton-proton collisions at s√=7s=7 and 8 TeV, corresponding to 5.0 and 19.7 fb−1, respectively, with the CMS experiment at the LHC. The cross ...
Study of Z boson production in pPb collisions at √sNN=5.02 TeV
(Elsevier, 2016-08-10)
The production of Z bosons in pPb collisions at View the MathML source is studied by the CMS experiment via the electron and muon decay channels. The inclusive cross section is compared to pp collision predictions, and ...
