Observation of eta(c) decay into Sigma(+)(Sigma)over-bar(-) and (sic)(-)((sic))over bar (+) final states
(American Physical Society, 2013-01-03)
Using a data sample of 2.25 x 10(8) J/psi events collected with the BESIII detector, we present the first observation of the decays of eta(c) mesons to Sigma(+)(Sigma) over bar (-) and (sic)(-)<((sic))over bar>(+) .The ...
Observation of the psi(1(3)D(2)) State in e(+)e(-) -> pi(+)pi(-)gamma chi(c1) at BESIII
(American Physical Society, 2015-07-01)
We report the observation of the X(3823) state in the process e(+)e(-) -> pi(+)pi(-) X(3823) pi(+)pi(-)gamma chi(c1) with a statistical significance of 6.2 sigma, in data samples at center-of-mass energies root s = 4.230, ...
