Possible Zero at a Wrong-Signature Sense Point in Backwardπ−pElastic Scattering

Abstract

A possible zero at the wrong-signature sense point ${\alpha }_{\Delta }=\frac{1}{2}$ on the exchanged ${\Delta }_{\delta }$ trajectory is suggested in connection with the new Cornell-Brookhaven National Laboratory experiments on the ${\pi }^{-}p$ backward peaks.
