Abstract
We calculate in the next-to-leading order the impact factor (vertex) for the production of a forward high- jet, in the approximation of small aperture of the jet cone in the pseudorapidity-azimuthal angle plane. The final expression for the vertex turns out to be simple and easy to implement in numerical calculations.
