Observation of ψ (3686) →n n ̄ and improved measurement of ψ (3686) →p p ̄
(Amer Physic Soc., 2019)We observe the process psi(3686) -> p (p) over bar eta' for the first time, with a statistical significance higher than 10 sigma, and measure the branching fraction of J/psi -> p (p) over bar eta' with an improved accuracy ... -
Precision Measurement of the Branching Fractions of eta ' Decays
(Amer Physic Soc., 2019-04-09)Based on a sample of (1310.6 +/- 7.0) x 10(6)J/psi events collected with the BESIII detector, we present measurements of J=. and. 0 absolute branching fractions using the process J/psi -> gamma eta'. By analyzing events ... -
Precision measurements of the e(+)e(-) -> (KSK +/-)-K-0 pi(-/+) Born cross sections at center-of-mass energies between 3.8 and 4.6 GeV
(Amer Physic Soc., 2019-04-11)Using data samples collected by the BESIII detector operating at the BEPCII storage ring, we measure the e(+)e(-) -> (KSK +/-)-K-0 pi(-/+ )Born cross sections at center-of-mass energies between 3.8 and 4.6 GeV, corresponding ... -
Search for baryon and lepton number violation in J/psi -> Lambda(+)(c)e(-) + c.c.
(Amer Physic Soc., 2019-04-12)Using 1.31 x 10(9) J/psi events collected by the BESIII detector at the Beijing Electron Positron Collider, we search for the process J/psi -> Lambda(+)(c)e(-) + c.c. for the first time. In this process, both baryon and ... -
