Pseudorapidity distributions of charged hadrons in proton-lead collisions at √sNN = 5.02 and 8.16 TeV
(Springer Berlin Heidelberg, 2018-01)
The pseudorapidity distributions of charged hadrons in proton-lead collisions at nucleon-nucleon center-of-mass energies √sNN = 5.02 and 8.16 TeV are presented. The measurements are based on data samples collected by the ...
Measurements of jet charge with dijet events in pp collisions at s=8$$ \sqrt{s}=8 $$ TeV
(Springer Nature, 2018-10-09)
Jet charge is an estimator of the electric charge of a quark, antiquark, or gluon initiating a jet. It is based on the momentum-weighted sum of the electric charges of the jet constituents. Measurements of three charge ...
Search for electroweak production of charginos and neutralinos in multilepton final states in proton-proton collisions at √s = 13 TeV
(Springer International Publishing AG, 2018-03)
Results are presented from a search for the direct electroweak production of charginos and neutralinos in signatures with either two or more leptons (electrons or muons) of the same electric charge, or with three or more ...
Measurement of prompt and nonprompt charmonium suppression in PbPb collisions at 5.02 TeV
(Springer Berlin Heidelberg, 2018-06)
The nuclear modification factors of J/ψ and ψ (2S) mesons are measured in PbPb collisions at a centre-of-mass energy per nucleon pair of √s[subscript NN] = 5.02 TeV. The analysis is based on PbPb
and pp data samples ...
Search for New Physics in Events with Two Soft Oppositely Charged Leptons and Missing Transverse Momentum in Proton–proton Collisions at √s = 13 TeV
(Elsevier, 2018-05)
A search is presented for new physics in events with two low-momentum, oppositely charged leptons (electrons or muons) and missing transverse momentum in proton-proton collisions at a centre-of-mass energy of 13 TeV. The ...
Search for low mass vector resonances decaying into quark-antiquark pairs in proton-proton collisions at √s = 13 TeV
(Springer International Publishing AG, 2018-04-12)
A search for narrow vector resonances decaying into quark-antiquark pairs is presented. The analysis is based on data collected in proton-proton collisions at s√=13 TeV with the CMS detector at the LHC, corresponding to ...
Constraints on the double-parton scattering cross section from same-sign W boson pair production in proton-proton collisions at √s = 8 TeV
(Springer International Publishing AG, 2018-02)
A first search for same-sign WW production via double-parton scattering is performed based on proton-proton collision data at a center-of-mass energy of 8 TeV using dimuon and electron-muon final states. The search is based ...
Measurement of the inclusive t[bar over t] cross section in pp collisions at √s = 5.02 TeV using final states with at least one charged lepton
(Springer Berlin Heidelberg, 2018-03)
The top quark pair production cross section (σ[subscript t[bar over t]]) is measured for the first time in pp collisions at a center-of-mass energy of 5.02 TeV. The data were collected by the CMS experiment at the LHC and ...
Search for supersymmetry in proton-proton collisions at 13 TeV using identified top quarks
(American Physical Society, 2018-01)
A search for supersymmetry is presented based on proton-proton collision events containing identified hadronically decaying top quarks, no leptons, and an imbalance p [superscript miss] [subscript T] in transverse momentum. ...
Comparing transverse momentum balance of b jet pairs in pp and PbPb collisions at sNN=5.02$$ \sqrt{s_{\mathrm{NN}}}=5.02 $$ TeV
(Springer, 2018-03)
The transverse momentum balance of pairs of back-to-back b quark jets in PbPb and pp collisions recorded with the CMS detector at the LHC is reported. The center-of-mass energy in both collision systems is 5.02 TeV per ...
