摘要With helicity partial wave analysis formalism, we discuss how one can distinguish f(0) resonance from f(2) resonance in the process of J/psi-->f(J)phi(theta(1), phi(1)) with f(J) -->pipi( theta(2), phi(2)) and phi-(K) over barK( theta(3), phi(3)) by various projections of angular distributions. We find that f(0) and f(2) can give the same one-dimensional angular distributions for I(theta(1)) boolean ORI(phi(1)) boolean ORI(theta(2)) boolean ORI(phi(2)), but cannot give the same I(theta(1)) boolean ORI(phi(1)) boolean ORI(theta(2)) boolean ORI(phi(2)) boolean ORI(phi(3)). So it is necessary to consider all three decay vertices in order to distinguish f(0) from f2 by one-dimensional projections of angular distributions.
