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 ...
Studies of B-s2*(5840)(0) and B-s1(5830)(0) mesons including the observation of the B-s2*(5840)(0) -> (BKS0)-K-0 decay in proton- proton collisions at root s=8 TeV
(Springer, 2018)
Measurements of B-s2*(5840)(0) and B-s1(5830)(0) mesons are performed using a data sample of proton-proton collisions corresponding to an integrated luminosity of 19.6 fb(-1), collected with the CMS detector at the LHC at ...
Search for Leptoquarks Coupled to Third-Generation Quarks in Proton-Proton Collisions at root s=13 TeV
(Amer Physical Soc, 2018)
Three of the most significant measured deviations from standard model predictions, the enhanced decay rate for B -> D-(*())tau nu, hints of lepton universality violation in B -> K-(*())ll decays, and the anomalous magnetic ...
Evidence for the Associated Production of a Single Top Quark and a Photon in Proton-Proton Collisions at root s=13 TeV
(Amer Physical Soc, 2018)
The first evidence of events consistent with the production of a single top quark in association with a photon is reported. The analysis is based on proton-proton collisions at root s = 13 TeV and recorded by the CMS ...
Observation of Higgs Boson Decay to Bottom Quarks
(Amer Physical Soc, 2018)
The observation of the standard model (SM) Higgs boson decay to a pair of bottom quarks is presented. The main contribution to this result is from processes in which Higgs bosons arc produced in association with a W or Z ...
Search for physics beyond the standard model in high-mass diphoton events from proton-proton collisions at root s=13 TeV
(Amer Physical Soc, 2018)
A search for physics beyond the standard model is performed using a sample of high-mass diphoton events produced in proton-proton collisions at root s = 13 TeV. The data sample was collected in 2016 with the CMS detector ...
