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 ...
Search for direct production of supersymmetric partners of the top quark in the all-jets final state in proton-proton collisions at √s = 13 TeV
(Springer Nature, 2017-10)
A search for direct production of top squark pairs in events with jets and large transverse momentum imbalance is presented. The data are based on proton-proton collisions at a center-of-mass energy of 13 TeV, collected ...
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 m[subscript jet] of top quark jets produced in t[bar over t] events from pp collisions at √s=8 TeV is reported for the jet with the largest transverse momentum p[subscript T] in highly ...
Search for High-Mass Z γ Resonances in Proton–proton Collisions At √s = 8 and 13 TeV Using Jet Substructure Techniques
(Elsevier, 2017-06)
A search for massive resonances decaying to a Z boson and a photon is performed in events with a hadronically decaying Z boson candidate, separately in light-quark and b quark decay modes, identified using jet substructure ...
Measurement of differential cross sections for top quark pair production using the Lepton + Jets Final State in Proton-Proton Collisions at 13 TeV
(American Physical Society, 2017-05)
Differential and double-differential cross sections for the production of top quark pairs in proton-proton collisions at 13 TeV are measured as a function of jet multiplicity and of kinematic variables of the top quarks ...
