Observation of the decays chi(cJ) -> nK(S)(0) (Lambda)over-bar + c.c.
(SPRINGER, 2021)
By analyzing 4.48 x 10(8) psi(3686) events collected with the BESIII detector, we observe the decays chi(cJ) -> nK(S)(0) (Lambda) over bar + c.c. (J = 0, 1, 2) for the first time, via the radiative transition psi(3686) -> ...
Measurement of branching fractions of J/psi and psi(3686) decays to Sigma(+) and (Sigma)over-bar(-)
(SPRINGER, 2021)
Using 1310.6 x 10(6) J/psi and 448.1 x 10(6) psi(3686) events collected with the BESIII detector, the branching fractions of J/psi decays to Sigma(+)(Sigma) over bar (-) is measured to be (10.61 +/- 0.04 +/- 0.36) x 10(-4), ...
Measurement of the absolute branching fractions of J/psi -> gamma eta and eta decay modes
(AMER PHYSICAL SOC, 2021)
Based on a data sample of (1.0087 +/- 0.0044) x 10(10) J/psi events collected by the BESIII detector at the BEPCII accelerator, the absolute branching fraction (BF) of the decay J/psi -> gamma eta is measured with high ...
Observation of psi (3686) ->Xi (1530)(0) (Xi)over-bar (1530)(0) and Xi (1530)(0) (Xi)over-bar(0)
(AMER PHYSICAL SOC, 2021)
Using (448.1 +/- 2.9) x 10(6) psi (3686) events collected with the BESIII detector and a single-baryon tagging technique, we present the first observation of the decays psi(3686)-> Xi (1530)(0) (Xi) over bar (1530)(0) and ...
