Total pion-proton cross-section from the new LHCf data on leading neutrons spectra

Abstract

In the light of the latest data by LHCf collaboration of the LHC on leading neutrons spectra it is possible to obtain total pion-proton cross-sections in the TeV energy region. In this work the exact extraction procedure is shown. Final numbers for the pion-proton cross-section are collected at several different values of the colliding energy and compared with some popular theoretical predictions. Errors of results are estimated.

5 pages, 6 figures, 1 table, results of this version are more correct than in the version 2. Figs 3, 6 and Table 1 are changed. Minor changes in the text. One reference is added. Erratum is sent to the EPJC
