We study next-to-leading gluon exchange in high-energy scattering that contributes to the amplitude to order s0 up to logarithmic corrections. Similar to the leading gluon exchange these contributions can be described in terms of Reggeon exchanges. There are several gluonic Reggeons at the next-to-leading level. Some of them transfer parity or gauge group representations different from the leading gluonic Reggeon. Unlike the leading one they are sensitive to the helicity and transverse momenta of the scattering partons. We extend the high-energy effective action and derive from the action of gluodynamics the terms describing the next-to-leading Reggeons and their interaction in the multi-Regge approximation.
