Observation of J/Psi Electromagnetic Dalitz Decays to X(1835), X(2120), and X(2370)
(American Physical Society, 2022)
Using a sample of about 1010 J/ψ events collected at a center-of-mass energy s=3.097 GeV with the BESIII detector, the electromagnetic Dalitz decays J/ψ→e+e-π+π-η′, with η′→γπ+π- and η′→π+π-η, have been studied. The decay ...
Observation of a State X(2600) in the pi(+) pi(-)eta' System in the Process J/psi -> gamma pi(+)pi(-)eta'
(American Physical Society, 2022)
Based on (10087±44)×106 J/ψ events collected with the BESIII detector, the process J/ψ→γπ+π-η′ is studied using two largest decay channels of the η′ meson, η′→γπ+π- and η′→ηπ+π-, η→γγ. A new resonance, which we denote as ...
Measurement of the e(+)e(-) -> Sigma(0)(Sigma)over-bar(0) cross sections at center-of-mass energies from 2.3864 to 3.0200 GeV
(ELSEVIER, 2022)
The Born cross sections of e(+)e(-) -> Sigma(0)(Sigma) over bar (0) are measured at center-of-mass energies from 2.3864 to 3.0200 GeV using data samples with an integrated luminosity of 328.5 pb(-1) collected with the ...
