Measurement of the branching fraction of $J / ψ \to ω η^{'} π^{+} π^{-}$ and search for $J / ψ \to ω X (1835), X (1835) \to η^{'} π^{+} π^{-}$ decay

BESIII Collaboration

Using a sample of $1.31 \times 1 0^{9}$ $J / ψ$ events collected by the BESIII detector at BEPCII during 2009 and 2012, we study the $J / ψ \to ω η^{'} π^{+} π^{-}$ hadronic process.…

Precise measurement of the $e^{+} e^{-} \to π^{+} π^{-} J / ψ$ cross section at center-of-mass energies from 3.77 to 4.60 GeV

M. Ablikim, M. N. Achasov, X. C. Ai +412

The cross section for the process $e^{+} e^{-} \to π^{+} π^{-} J / ψ$ is measured precisely at center-of-mass energies from 3.77 to 4.60~GeV using 9~fb $^{- 1}$ of data collected with the BESIII d…

Is the $J^{P} = 2^{-}$ assignment for the $X (3872)$ compatible with the radiative transition data?

Yu Jia, Wen-Long Sang, Jia Xu

The very recent analysis by BaBar Collaboration indicates that the $X (3872)$ may favor the quantum number $J^{P C} = 2^{-+}$ rather than the previously assumed $1^{++}$ . By pretending…
