讨论了 2 → 3 粒子反应的二元性的一般含义。明确表明，双五点振幅预测渐近违反了与线反转相关的准二体过程的微分截面的通常相等性。例如，交换简并模型预测 [Formula: see text] 但预测 [Formula: see text] 。这种效应是由最终状态下竞争的两体通道之间的干扰引起的。
General implications of duality for 2 → 3 particle reactions are discussed. It is shown explicitly that dual five-point amplitudes predict asymptotic violation of the usual equality of differential cross-sections for quasi-two-body processes related by line-reversal. For example, an exchange degenerate model predicts [Formula: see text] but [Formula: see text] . This effect arises from interference between competing two-body channels in the final state.
