We discuss single inclusive hadron production from a high-energy quark scattering off a strong target color field in the color glass condensate formalism. Recent calculations of this process at the next-toleading-order accuracy have led to negative cross sections at large transverse momenta. We identify the origin of this problem as an oversubtraction of the rapidity divergence into the Balitsky-Kovchegov evolution equation for the target. We propose a new way to implement the kinematical restriction on the emitted gluons to overcome this difficulty.

Balitsky-Kovchegov equation at next-to-leading order accuracy with a resummation of large logarithms Lappi, Tuomas; Mäntysaari, H. (Sissa, 2016)We include resummation of large transverse logarithms into the next-to-leading order BalitskyKovchegov equation. The resummed NLO evolution equation is shown to be stable, the evolution speed being significantly reduced ...
Small-x Physics in the Dipole Picture at NLO Accuracy Iancu, Edmond; Lappi, Tuomas; Triantafyllopoulos, Dionysios (World Scientific, 2020)We review recent progress in NLO calculations for dilute-dense processes in the CGC picture. In particular, we focus here on recent steps in understanding high energy renormalization group evolution (BK/JIMWLK), the total ...
On the use of a running coupling in the calculation of forward hadron production at next-to-leading order Ducloué, B.; Iancu, E.; Lappi, Tuomas; Mueller, A.H.; Soyez, G.; Triantafyllopoulos, D.N. (Elsevier BV, 2019)
Solving the NLO BK equation in coordinate space Lappi, Tuomas; Mäntysaari, Heikki (Sissa, 2015)We present results from a numerical solution of the next-to-leading order (NLO) BalitskyKovchegov (BK) equation in coordinate space in the large Nc limit. We show that the solution is not stable for initial conditions ...
Implementation of NLO high energy factorization in single inclusive forward hadron production Ducloue, Bertrand; Lappi, Tuomas; Zhu, Yan (American Physical Society, 2017)Single inclusive particle production cross sections in high energy hadron collisions at forward rapidity are an important benchmark process for the Color Glass Condensate picture of small x QCD. Recent calculations of ...
