Query: Diphoton production at Tevatron and the LHC in the NLO* approximation of
  the Parton Reggeization Approach   The hadroproduction of prompt isolated photon pairs at high energies is
studied in the NLO* framework of the Parton Reggeization Approach. The real
part of the NLO corrections is computed, and the procedure for the subtraction
of double counting between real parton emissions in the hard-scattering matrix
element and unintegrated PDF is constructed for the amplitudes with Reggeized
quarks in the initial state. The matrix element of the important NNLO
subprocess RR->2gamma with full dependence on the transverse momenta of the
initial-state Reggeized gluons is obtained. We compare obtained numerical
results with diphoton spectra measured at Tevatron and the LHC, and find a good
agreement of our predictions with experimental data at the high values of
diphoton transverse momentum, pT, and especially at the pT larger than the
diphoton invariant mass, M. In this multi-Regge kinematics region, the NLO
correction is strongly suppressed, demonstrating the self-consistency of the
Parton Reggeization Approach.
