摘要
Considering the Froissart-Martin bound, Jin-Martin-Cornille bound and the optical theorem, we propose a novel parametrization for the total cross-section of proton-proton and antiproton-proton elastic scattering data. Using derivative dispersion relations we obtain the real part of the elastic scattering amplitude and thus the rho parameter. Simultaneous fits to sigma tot and rho are performed allowing very good statistical descriptions of the available data. Furthermore, predictions to sigma tot and rho at energies not used in the fit procedures are presented. For stot we obtain predictions at RHIC, LHC and future hadron collider energies.
