The Ɩ/E Puzzle and the Moment Analysis

  •  Center of Theoretical Physics, CCAST Lab. and Institute of High Energy Physics, Chinese Academy of Science, Beijing

  • We introduce the photon angular distribution for the moment of the process e+e-→J/ψ→γB, B→P1P2P3 to discuss the (Ɩ/E puzzle. It provides a criterion to distinguish the 0-+ state from the 1++ state in the process e+e-→J/ψ→γKKπ.

Abstract: We introduce the photon angular distribution for the moment of the process e+e-→J/ψ→γB, B→P1P2P3 to discuss the (Ɩ/E puzzle. It provides a criterion to distinguish the 0-+ state from the 1++ state in the process e+e-→J/ψ→γKKπ.
