Measurements of (tt)over-barH Production and the CP Structure of the Yukawa Interaction between the Higgs Boson and Top Quark in the Diphoton Decay Channel
(Amer Physical Soc, 2020)
The first observation of the (tt) over barH process in a single Higgs boson decay channel with the full reconstruction of the final state (H -> gamma gamma) is presented, with a significance of 6.6 standard deviations ...
Measurement of B-c(2S)(+) and B-c*(2S)(+) cross section ratios in proton-proton collisions at root s=13 TeV
(Amer Physical Soc, 2020)
The ratios of the B-c (2S)(+) to B-c(+), B-c(*)(2S)(+) to B-c(+), and Bc(2S)(+) to Bco2STHORNthorn production cross sections are measured in proton-proton collisions at root s = 13 TeV, using a data sample collected by the ...
Evidence for Top Quark Production in Nucleus-Nucleus Collisions
(Amer Physical Soc, 2020)
Ultrarelativistic heavy ion collisions recreate in the laboratory the thermodynamical conditions prevailing in the early universe up to 10(-6) sec, thereby allowing the study of the quark-gluon plasma (QGP), a state of ...
Observation of the Production of Three Massive Gauge Bosons at root s=13 TeV
(Amer Physical Soc, 2020)
The first observation is reported of the combined production of three massive gauge bosons (VVV with V = W, Z) in proton-proton collisions at a center-of-mass energy of 13 TeV. The analysis is based on a data sample recorded ...
Observation of the B-s(0) -> X(3872)phi Decay
(Amer Physical Soc, 2020)
Using a data sample of proton-proton collisions at root s = 13 TeV, corresponding to an integrated luminosity of 140 fb(-1) collected by the CMS experiment in 2016-2018, the B-s(0) -> X(3872)phi decay is observed. Decays ...
Measurements of the W boson rapidity, helicity, double-differential cross sections, and charge asymmetry in pp collisions at root s=13 TeV
(Amer Physical Soc, 2020)
The differential cross section and charge asymmetry for inclusive W boson production at root s = 13 TeV is measured for the two transverse polarization states as a function of the W boson absolute rapidity. The measurement ...
Search for physics beyond the standard model in events with jets and two same-sign or at least three charged leptons in proton-proton collisions at <mml:msqrt>s</mml:msqrt>=13 TeV
(Springer, 2020)
A data sample of events from proton-proton collisions with at least two jets, and two isolated same-sign or three or more charged leptons, is studied in a search for signatures of new physics phenomena. The data correspond ...
Search for supersymmetry in pp collisions at root s=13 TeV with 137 fb(-1) in final states with a single lepton using the sum of masses of large-radius jets
(Amer Physical Soc, 2020)
Results are reported from a search for new physics beyond the standard model in proton-proton collisions in final states with a single lepton; multiple jets, including at least one jet tagged as originating from the ...
W+ W- boson pair production in proton-proton collisions at root s=13 TeV
(Amer Physical Soc, 2020)
A measurement of the W+W- boson pair production cross section in proton-proton collisions at root s = 13 TeV is presented. The data used in this study are collected with the CMS detector at the CERN LHC and correspond to ...
Measurement of the top quark Yukawa coupling from t(t)over-bar kinematic distributions in the dilepton final state in proton-proton collisions at root s=13 TeV
(Amer Physical Soc, 2020)
A measurement of the Higgs boson Yukawa coupling to the top quark is presented using proton-proton collision data at root s = 13 TeV, corresponding to an integrated luminosity of 137 fb(-1), recorded with the CMS detector. ...
