Search for standard model production of four top quarks with same-sign and multilepton final states in proton-proton collisions at root s=13TeV
(Springer, 2018)
A search for standard model production of four top quarks (t (t) over bart (t) over bar) is reported using events containing at least three leptons (e, mu) or a same-sign lepton pair. The events are produced in proton-proton ...
Elliptic Flow of Charm and Strange Hadrons in High-Multiplicity p plus Pb Collisions at root(NN)-N-s=8.16 TeV
(Amer Physical Soc, 2018)
The elliptic azimuthal anisotropy coefficient (upsilon(2)) is measured for charm (D-0) and strange (K-S(0), Lambda, Xi(-), and Omega(-)) hadrons, using a data sample of p + Pb collisions collected by the CMS experiment, ...
Observation of the Z -> psi l(+)l(-) Decay in pp Collisions at root s=13 TeV
(Amer Physical Soc, 2018)
This Letter presents the observation of the rare Z boson decay Z -> psi l(+)l(-). Here, psi represents contributions from direct J/psi and psi(2S) -> J/psi X, l(+)l(-) is a pair of electrons or muons, and the J/psi meson ...
Search for Narrow Resonances in the b-Tagged Dijet Mass Spectrum in Proton-Proton Collisions at root s=8 TeV
(Amer Physical Soc, 2018)
A search for narrow resonances decaying to bottom quark-antiquark pairs is presented, using a data sample of proton-proton collisions at root s = 8 TeV corresponding to an integrated luminosity of 19.7 fb(-1). The search ...
Search for Physics Beyond the Standard Model in Events with High-Momentum Higgs Bosons and Missing Transverse Momentum in Proton-Proton Collisions at 13 TeV
(Amer Physical Soc, 2018)
A search for physics beyond the standard model in events with one or more high-momentum Higgs bosons, H, decaying to pairs of b quarks in association with missing transverse momentum is presented. The data, corresponding ...
Search for pair production of excited top quarks in the lepton plus jets final state the CMS Collaboration
(Elsevier, 2018)
A search is performed for the pair production of spin-3/2 excited top quarks, each decaying to a top quark and a gluon. The search uses the data collected with the CMS detector from proton-proton collisions at a center-of-mass ...
Measurement of differential cross sections for the production of top quark pairs and of additional jets in lepton plus jets events from pp collisions at root s=13 TeV
(Amer Physical Soc, 2018)
Differential and double-differential cross sections for the production of top quark pairs in proton-proton collisions at root s = 13 TeV are measured as a function of kinematic variables of the top quarks and the top ...
Search for supersymmetry in multijet events with missing transverse momentum in proton-proton collisions at 13 TeV
(Amer Physical Soc, 2017)
A search for supersymmetry is presented based on multijet events with large missing transverse momentum produced in proton-proton collisions at a center-of-mass energy of root s = 13 TeV. The data, corresponding to an ...
Measurement of the differential cross sections for the associated production of a W boson and jets in proton-proton collisions at root s=13 TeV
(Amer Physical Soc, 2017)
A measurement of the differential cross sections for a W boson produced in association with jets in the muon decay channel is presented. The measurement is based on 13 TeV proton-proton collision data corresponding to an ...
Search for an L-mu - L-tau gauge boson using Z -> 4 mu events in proton-proton collisions at root s=13 TeV
(Elsevier, 2019)
A search for a narrow Z' gauge boson with a mass between 5 and 70 GeV resulting from an L-mu - L-tau U (1) local gauge symmetry is reported. Theories that predict such a particle have been proposed as an explanation of ...
