Evidence for BFKL and saturation dynamics from di-hadron spectra at the LHC

Abstract

We demonstrate that rapidity separated di-hadron spectra in high multiplicity proton-proton collisions at the LHC can be quantitatively described by a combination of BFKL and saturation dynamics. Based on these results, we predict the systematics of di-hadron spectra in proton-nucleus collisions at the LHC.

9 pages, 5 figures. v3 corrects for a numerical error in the BFKL cross-section for asymmetric collisions, modifying fig. 5. Figs. 2-4 containing the main results of the paper remain unchanged
