Evidence for e(+)e(-) -> gamma eta(c)(1S) at center-of-mass energies between 4.01 and 4.60 GeV
(Amer Physical Soc., 2017)
We present first evidence for the process e(+)e(-) -> gamma eta(c)(1S) at six center-of-mass energies between 4.01 and 4.60 GeV using data collected by the BESIII experiment operating at BEPCII. We measure the Born cross ...
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 ...
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 ...
