In this work, we investigate the X(3915) and Z(3930) decays into J/ψω with the χ  c0(2P) and χ  c2(2P) assignments to X(3915) and Z(3930), respectively. The results show that the decay width of Z(3930) → J/ψω is at least one order smaller than that of X(3915) → J/ψω. This observation explains why only one structure, X(3915), has been observe…
