  Azimuthal angle decorrelation in inclusive dijet cross sections is studied
analytically to take into account the next-to-leading corrections to the BFKL
kernel while keeping the jet vertices at leading order. The spectral
representation on the basis of leading order eigenfunctions is generalized to
include the dependence on conformal spins. With this procedure running coupling
effects and angular dependences are both included. It is shown how the angular
decorrelation for jets with a wide relative separation in rapidity largely
decreases at this higher order in the resummation.
