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 ...
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 ...
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 ...
Measurements of pp -> ZZ production cross sections and constraints on anomalous triple gauge couplings at root s=13 TeV
(Springer, 2021)
The production of Z boson pairs in proton-proton (pp) collisions, pp -> (Z/gamma*)(Z/gamma*) -> 2l2l', where l, l' = e or mu, is studied at a center-of-mass energy of 13 TeV with the CMS detector at the CERN LHC. The data ...
Search for a Narrow Resonance Lighter than 200 GeV Decaying to a Pair of Muons in Proton-Proton Collisions at root s=13 TeV
(Amer Physical Soc, 2020)
A search is presented for a narrow resonance decaying to a pair of oppositely charged muons using root s = 13 TeV proton-proton collision data recorded at the LHC. In the 45-75 and 110-200 GeV resonance mass ranges, the ...
Search for top squark pair production using dilepton final states in pp collision data collected at root s=13TeV
(Springer, 2021)
A search is presented for supersymmetric partners of the top quark (top squarks) in final states with two oppositely charged leptons (electrons or muons), jets identified as originating from bquarks, and missing transverse ...
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 ...
