Search for the Isoscalar 1-+ Exotic State at BEPC/BES

  • A possibility to search for the isoscalar 1-+ exotic state through the J/ψ decay process J/ψ→V+X,X→a2+π at BEPC/BES is discussed in two cases of single state and two-state coupling.The results show that this possibility is existent both in J/ψ radiative decay and hadronic decay processes.

Abstract: A possibility to search for the isoscalar 1-+ exotic state through the J/ψ decay process J/ψ→V+X,X→a2+π at BEPC/BES is discussed in two cases of single state and two-state coupling.The results show that this possibility is existent both in J/ψ radiative decay and hadronic decay processes.
