Analytic parameterization of high-energy forward scattering amplitude. I : $p \overline{p}$ and $pp$ scattering

The pp and pp forward scattering amplitude F(E) is represented in a parametric form which is analytic in the cut E plane and which gives the asymptotic behaviour of the total cross sections sigma (pp), sigma (pp) approximately (log E/E/sub 0/)/sup gamma /, E being the lab energy and gamma being real...

description The pp and pp forward scattering amplitude F(E) is represented in a parametric form which is analytic in the cut E plane and which gives the asymptotic behaviour of the total cross sections sigma (pp), sigma (pp) approximately (log E/E/sub 0/)/sup gamma /, E being the lab energy and gamma being real. Fits to high energy data favour a (log E /E/sub o/)/sup 2/ increase of sigma (pp) for E to infinity , but admit also other growth rates. The predicted real part of the forward amplitude becomes positive at E about 300 GeV and is equal to 6-10% of the imaginary part at 2000 GeV. (16 refs).
