Real next-to-leading corrections to the multigluon amplitudes in the helicity formalism

Using the helicity formalism, we compute the corrections to the tree-level multigluon amplitudes in the high-energy limit, induced by the corrections to the multi-Regge kinematics, and we show that they coincide with the corresponding Fadin-Lipatov amplitudes at fixed helicities. copyright 1996 The American Physical Society
