Abstract
The crossing relation for transversity amplitudes is used in a simple proof of the kinematic‐singularity structure of helicity amplitudes, both in the general‐mass and in various particular‐mass cases. A comparison with earlier results is made. The kinematic properties of helicity and transversity amplitudes are employed in the derivation of an asymptotic expression for the contribution of Regge poles to the amplitude.Keywords
