Towards the test of saturation physics beyond leading logarithm.

摘要: We present results from the first next-to-leading-order (NLO) numerical analysis of forward hadron production in $pA$ and $dA$ collisions small-$x$ saturation formalism. Using parton distributions fragmentation functions at NLO, as well dipole amplitude solution to Balitsky-Kovchegov equation with running coupling, together NLO corrections hard coefficients, we obtain a good description available RHIC data $d\mathrm{Au}$ collisions. In large ${p}_{\ensuremath{\perp}}$ region beyond scale, find that correction becomes dominant negative, which indicates other physics important should also be taken into account. Furthermore, make predictions for $p\mathrm{Pb}$ LHC. This not only incorporates all partonic channels, but reduces renormalization scale dependence helps significantly reduce theoretical uncertainties. It therefore provides precise test leading logarithmic approximation.
