Truncated BFKL Series and Hadronic Collisions

Abstract

A truncated BFKL series is studied and applied to hadronic processes. The proton-(anti)proton cross sections are described with good agreement with data and in a way consistent with the unitarity bound. The elastic scattering amplitude is calculated at momentum transfer $t$ different from zero, introducing two distinct ansatze for the proton impact factor. The elastic differential cross section is obtained at small $t$ approximation and compared with the data.
