Description
The relationship between Regge theory and the formalism of Collins-Soper-Sterman is explored by considering the off lightcone effects induced in color octet exchange in $2\to2$ forward scattering. An attempt to unify the language of rapidity divergences and high-energy asymptotic behavior is presented, with insights on the extensions of $k_T$-factorization beyond leading-log accuracy and the role of Collins-Soper kernel in characterizing the Regge trajectory.
