Parametrization of the $\bar PP$ Elastic Scattering Differential Cross Section Between 2 GeV/c $\leq P_{lab}\leq$ 16 GeV/c

Abstract

A parameterization of the $\bar pp$ differential elastic scattering cross section in the beam momentum range from 2 to 16 GeV/c is proposed. The parameterization well describes the existing data including the observed diffraction pattern at four-momentum transfer $|t|$ up to 1.5-2.0 GeV$^2$. It can be used for detailed calculations of the radiation load on the detectors being designed for the PANDA detector at the future FAIR facility in Darmstadt.
