Description
A general framework for the description of semi-hard scattering amplitudes in perturbative Quantum Chromodynamics (pQCD) is presented, based on the use of the next-to-leading order eigenfunctions of the Balitsky–Fadin–Kuraev–Lipatov (BFKL) kernel constructed by Chirilli and Kovchegov. Formal aspects related to the consistency with the corresponding formulation employing leading-order BFKL eigenfunctions are discussed. The phenomenological implications of adopting either representation are investigated through a comparative analysis of the resulting amplitudes in selected high-energy processes.
