Measurements of the tt production cross section in lepton+jets final states in pp collisions at 8 TeV and ratio of 8 to 7 TeV cross sections
(Springer Nature, 2017)
© 2017, CERN for the benefit of the CMS collaboration. A measurement of the top quark pair production (tt¯) cross section in proton–proton collisions at the centre-of-mass energy of 8TeV is presented using data collected ...
Measurement of Double-Differential Cross Sections for Top Quark Pair Production in Pp Collisions at √s = 8 TeV and Impact on Parton Distribution Functions
(Springer/Società Italiana di Fisica, 2017-07)
Normalized double-differential cross sections for top quark pair (t[bar over t]) production are measured in pp collisions at a centre-of-mass energy of 8 TeV with the CMS experiment at the LHC. The analyzed data correspond ...
Measurement of electroweak-induced production of Wγ with two jets in pp collisions at √s = 8 TeV and constraints on anomalous quartic gauge couplings
(Springer Nature, 2017-06)
A measurement of electroweak-induced production of Wγ and two jets is performed, where the W boson decays leptonically. The data used in the analysis correspond to an integrated luminosity of 19.7 fb−1collected by the CMS ...
Search for supersymmetry in events with at least one photon, missing transverse momentum, and large transverse event activity in proton-proton collisions at √s = 13 TeV
(Springer Berlin Heidelberg, 2017-12)
A search for physics beyond the standard model in final states with at least one photon, large transverse momentum imbalance, and large total transverse event activity is presented. Such topologies can be produced in ...
Principal-component analysis of two-particle azimuthal correlations in PbPb and and pPb collisions at CMS
(American Physical Society, 2017-12)
For the first time a principle-component analysis is used to separate out different orthogonal modes of the two-particle correlation matrix from heavy ion collisions. The analysis uses data from √s[subscript NN] = 2.76 ...
Coherent J/ ψ Photoproduction in Ultra-Peripheral PbPb Collisions at √s[subscript NN = 2.76 TeV with the CMS Experiment
(Elsevier BV, 2017-07)
The cross section for coherent J/ψ photoproduction accompanied by at least one neutron on one side of the interaction point and no neutron activity on the other side, X[subscript n]0[subscript n], is measured with the CMS ...
Measurement of the jet mass in highly boosted t[bar over t] events from pp collisions at √s=8 TeV
(Springer/Società Italiana di Fisica, 2017-07)
The first measurement of the jet mass mjet of top quark jets produced in tt¯ events from pp collisions at √s=8 TeV is reported for the jet with the largest transverse momentum pT in highly boosted hadronic top quark decays. ...
Search for dark matter and unparticles in events with a Z boson and missing transverse momentum in proton-proton collisions at √s = 13 TeV
(Springer Nature, 2017-03)
A search for dark matter and unparticle production at the LHC has been performed using events containing two charged leptons (electrons or muons), consistent with the decay of a Z boson, and large missing transverse momentum. ...
Search for Heavy Resonances Decaying to Tau Lepton Pairs in Proton-Proton Collisions at √s = 13 TeV
(Springer Nature, 2017-02)
A search for heavy resonances that decay to tau lepton pairs is performed using proton-proton collisions at √s = 13 TeV. The data were collected with the CMS detector at the CERN LHC and correspond to an integrated luminosity ...
Search for heavy neutrinos or third-generation leptoquarks in final states with two hadronically decaying τ leptons and two jets in proton-proton collisions at s=13$$ \sqrt{s}=13 $$ TeV
(Springer Nature, 2017-03)
A search for new particles has been conducted using events with two high transverse momentum (pT) τ leptons that decay hadronically, at least two high-pT jets, and missing transverse energy from the τ lepton decays. The ...
