英文摘要We conjecture that Z(c)(-)(4100) found by the LHCb group from a Dalitz plot analysis of B-0 ->eta K-c(+)pi(-) decay is the charge conjugate of Z(1)(+)(4050) observed in chi(c1)pi(+) distribution from the Belle collaboration. Some interesting conclusions are inferred from this assumption. The Z(2)(+)(4250) would be assigned to be a J(P)=1(+) or 1(-) state because of its absence in eta(c)pi(-) invariant mass distribution, while Z(1)(+)(4050)/Z(c)(-)(4100) could be a 0(+) or 1(-) state but 2(+) is unfavored because it would be coupled to eta(c)pi in D-wave. The null observation of Z(1)Z(2), Z(1)Z(1), and Z(2)Z(2) production in e(+)e(-) annihilation and Upsilon(1S,2S) decay by the Belle collaboration would further allocate the spin parity combination of Z(1)(+)(4050)/Z(c)(-)(4100) and Z(2)(+)(4250). Our deductions can be used to exclude a set of proposed models and could be further tested by future experiment, e.g., in gamma gamma collisions.
