  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-to-leading 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.
