Broadening and saturation effects in dijet azimuthal correlations in p-p and p-Pb collisions at sNN=5.02TeV

Abstract

We demonstrate that the recent forward-forward dijet correlation data measured by the ATLAS collaboration for proton-proton and proton-lead collisions are consistent with the broadening effects due to both the gluon saturation and the resummation of large logarithms of a hard scale (the so-called Sudakov logarithms). We find that both effects are necessary to describe the experimental results.
