Query: Parametrization of proton-proton total cross section from 10 GeV to 100
  TeV   Present estimations of proton-proton total cross section at very high
energies are obtained from cosmic rays (>10^17 eV) by means of some
approximations and the knowledge of the measured proton-air cross section at
these energies. Besides, total cross section are measured with present day high
energy colliders up to nearly 2 TeV in the center of mass (~ 10^15 eV in the
laboratory). Here we use a phenomenological model based on the
Multiple-Diffraction approach to succesfully describe data at accelerator
energies. Then we estimate with it proton-proton total cross sections at cosmic
ray energies. On the basis of a forecasting regression analysis we determine
confident errors bands, analyzing the sensitivity of our predictions to the
employed data for extrapolation.
