The decay of the observed $J^{PC}=1^{-+}$ (1400) and $J^{PC}=1^{-+}$(1600) hybrid candidates

F. Iddir, A. S. Safir

We study the possible interpretation of the two exotic resonances $J^{PC}=1^{-+}$ at 1400 and 1600 MeV, claimed to be observed by BNL, decaying respectively into $\eta \pi$, ${\eta }^{\prime }\pi$, $f_{…
