Abstract
We calculate in next-to-leading order BFKL the jet vertex relevant for the production of Mueller-Navelet jets in proton collisions and of forward jets in deep inelastic scattering. Starting from the denition of the totally inclusive quark and gluon impact factors in the BFKL approach and suitably considering the parton densities and the jet selection functions, we show that an infrared- free result can be found for the jet vertex. Finally we compare our expression for the vertex with the previous calculation of Refs. 1).File in questo prodotto:
