Azimuthal decorrelation of forward and backward jets at the Tevatron

We analyse the azimuthal decorrelation of ‘Mueller–Navelet’ dijets produced in the pp̄ collisions at Tevatron energies using a BFKL framework which incorporates dominant subleading effects. We show that these effects significantly reduce the decorrelation yet they are still insufficient to give satisfactory description of experimental data. However a good description of the data is obtained after incorporating within formalism the effective rapidity defined by Del Duca and Schmidt.
