N2 - Recent measurements of the inelastic and total proton-proton cross section at the LHC, and at cosmic ray energies by the Auger experiment, have quantitatively confirmed fits to lower energy data constrained by the assumption that the proton is asymptotically a black disk of gluons. We show that data on p̄(p)p, π -p, and K -p forward scattering support the related expectation that the asymptotic behavior of all cross sections is flavor independent. By using the most recent measurements from ATLAS, CMS, TOTEM, and Auger, we predict σtotpp(√s=8TeV)=100.6±2.9mb and σtotpp(√s=14TeV)=110.8±3.5mb, as well as refine the total cross section σtotpp(√s=57TeV)=139.6±5.4mb. Our analysis also predicts the total π -π + cross sections as a function of √s.
