| 英文摘要 | We present a derivation of coherent helicity amplitudes for a particle decaying into multifinal states with nonzero spins. the results show that the coherent amplitudes introduce additional rotations to transform the helicities into a consistent helicity system, which allows us to add helicity amplitudes for different decay chains coherently. these rotations may have significant effects on the interference between the decay chains in the partial wave analysis. |
