Observation and study of the decay J/psi -> phi eta eta '
(Amer Physical Soc., 2019)
We report the observation and study of the decay J/psi -> phi eta eta' phi eta eta' using 1.3 x 10(9) J/psi events collected with the BESIII detector. Its branching fraction, including all possible intermediate states, is ...
Study of e(+)e(-) -> gamma omega J/psi and Observation of X(3872) -> omega J/psi
(Amer Physical Soc., 2019)
We study the e(+)e(-) -> gamma omega J/psi process using 11.6 fb(-1) e(+)e(-) annihilation data taken at center-of-mass energies from root s = 4.008 GeV to 4.600 GeV with the BESIII detector at the BEPCII storage ring. The ...
