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 e(+)e(-)-> K+K-pi(0) cross section and observation of a resonant structure
(SPRINGER, 2022)
Based on e(+)e(-) collision data collected by the BESIII detector at the BEPCII collider at center-of-mass energies from 2.000 to 3.080 GeV, a partial-wave analysis is performed for the process e(+)e(-)-> K+K-pi(0). The ...
