Abstract
We update our eikonal fit and comprehensive asymptotic fits to high-energy data on proton-proton and antiproton-proton scattering for , , , , and . The fits include the new TOTEM values of the total proton-proton cross section, , and at , the Telescope Array value of the total proton-proton cross section at , and data from the latest measurements of the inelastic cross sections at (by TOTEM and ATLAS) and 13 TeV (by CMS, ATLAS, and TOTEM). An important new feature of this work is the correction of the data to include the effects of curvature in on the values of , at , and obtained by extrapolation from the larger values of where the differential cross section is measured, The effects are significant. The stability of the fits is excellent, and the new results agree well with the predictions of earlier fits. This work again confirms the evidence for the proton asymptotically becoming a black disk of gluons.
