Remarks on the UA4/2 d\sigma/dt and on the Asymptotic \sigma_T(s) Behavior

Abstract

We find that the UA4/2 measurements on the real part of the forward $p \bar p$ scattering amplitude and total cross section are consistent with each other and also with the standard picture of the Pomeron of either ${\it ln} ^2 s$ or ${\it ln} s$ type. However the asymptotic $\sigma _T (s)$ behavior obtained from the {\it ad hoc} parametrization fit to the $p \bar p$ total cross sections as quoted in the Review of Particle Properties is consistent with the analysis of the class of the analytic amplitude models that contain the ${\it ln} ^2 s$ type Pomeron term.
