p – air production cross-section and uncorrelated mini-jets processes in pp-scattering Fagundes, Daniel A. Grau, A. Pancheri, G. Srivastava, Y. N. Shekhovtsova, O. Cosmic rays Astro-particle physics For the p – air production cross-section, we use a Glauber formalism which inputs the pp inelastic cross-section from a mini-jet model embedded in a single-channel eikonal expression, that provides the needed contribution of uncorrelated processes. It is then shown that current LO parton density functions for the pp mini-jet cross-sections, with a rise tempered by acollinearity induced by soft gluon re-summation, are well suited to reproduce recent cosmic ray results. By comparing results for GRV, MRST72 and MSTW parametrizations, we estimate the uncertainty related to the low-x behavior of these densities. 2015-09-03T11:30:50Z 2015-09-03T11:30:50Z 2015 info:eu-repo/semantics/article Fagundes, D.A.; et al. p – air production cross-section and uncorrelated mini-jets processes in pp-scattering.
