Regge trajectory of a gluon in the two-loop approximation
Fadin V. S.
The Regge trajectory of a gluon in QCD is constructed in the two-loop approximation. It is found from the amplitude for quark-quark scattering with gluon quantum numbers in the t channel, calculated at a logarithmic (logs) accuracy in the two-loop approximation for asymptotically large energies л/s and for a fixed momentum transfer 4~~t© 1995 American Institute of Physics.
