Phase motion in the Z−(4430) amplitude in B0→ψ′π−K+ decay
In view of the proliferation in the number of new charmonium states, it is really important to have an experimental way to prove that an observed bump is, indeed, a real resonance. To do that, in this paper we present an alternative method to demonstrate the resonant behavior of a state. With this m...
