Dip Cancellation by an Interference Phenomenon

Exchange-degenerate pairs of Regge trajectories are shown to interfere in such a way that the wrong-signature nonsense zeros, which often lead to dips, are cancelled. The particular example of backward $K^{+}p$ scattering is discussed. It is shown to be plausible that the ${\Lambda }_{\alpha }$ and ${\Lambda }_{\gamma }$ trajectories in this reaction are degenerate. Thus, the dips expected when $\alpha \left({\Lambda }_{\alpha }\right)=-\frac{1}{2}$ and $\alpha \left({\Lambda }_{\gamma }\right)=-\frac{3}{2}$ may be cancelled by this mechanism.
