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 ...
Branching fraction measurement of J=Psi -> KSKL and search for J=Psi -> KSKS
(Amer Physical Soc., 2017)
Using a sample of 1.31 x 10(9) J/Psi events collected with the BESIII detector at the BEPCII collider, we study the decays of J/Psi -> KSKL and KSKS. The branching fraction of J/Psi -> KSKL is determined to be B(J/Psi -> ...
Searching for beauty-fully bound tetraquarks using lattice nonrelativistic QCD
(American Physical Society, 2018)
Using a data sample of (448.1±2.9)×106 ?(3686) events collected with the BESIII detector at the BEPCII collider, we present measurements of branching fractions for the decays ?cJ??+?- and ?0?0. The decays ?c1,2??+?- and ...
Observation of e +e - › ? 0? 0hc and a neutral charmoniumlike structure Zc(4020)0
(2014)
Using data collected with the BESIII detector operating at the Beijing Electron Positron Collider at center-of-mass energies of s?=4.23, 4.26, and 4.36 GeV, we observe e+e-›?0?0hc for the first time. The Born cross sections ...
