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 ...
Search for disappearing tracks in proton-proton collisions at root s=13 TeV
(Elsevier, 2020)
A search is presented for long-lived charged particles that decay within the volume of the silicon tracker of the CMS experiment. Such particles can produce events with an isolated track that is missing hits in the outermost ...
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 ...
Search for dijet resonances using events with three jets in proton-proton collisions at root s=13 TeV
(Elsevier, 2020)
A search for a narrow resonance with a mass between 350 and 700 GeV, and decaying into a pair of jets, is performed using proton-proton collision events containing at least three jets. The data sample corresponds to an ...
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 ...
Study of excited Lambda(0)(b) states decaying to Lambda(0)(b)pi(+)pi(-) in proton-proton collisions at root s=13TeV
(Elsevier, 2020)
A study of excited Lambda(0)(b) baryons is reported, based on a data sample collected in 2016-2018 with the CMS detector at the LHC in proton-proton collisions at a center-of-mass energy of 13 TeV, corresponding to an ...
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 ...
