Violation of energy–momentum conservation in Mueller–Navelet jets production

Abstract

We study effects related to violation of energy–momentum conservation inherent to the BFKL approach, in the particular case of Mueller–Navelet jets production. We argue, based on the comparison of the lowest order non-trivial corrections O(αs3) to the cross section with predictions of an exact calculation, that the inclusion of next-to-leading order BFKL corrections to the jet production vertex significantly reduces the importance of these effects.
