The BFKL equation, Mueller-Navelet jets and single-valued harmonic polylogarithms
نویسندگان
چکیده
We introduce a generating function for the coefficients of the leading logarithmic BFKL Green’s function in transverse-momentum space, order by order in αS, in terms of single-valued harmonic polylogarithms. As an application, we exhibit fully analytic azimuthal-angle and transverse-momentum distributions for Mueller-Navelet jet cross sections at each order in αS. We also provide a generating function for the total cross section valid to any number of loops.

BFKL NLL phenomenology of forward jets at HERA and Mueller Navelet jets at the Tevatron and the LHC
Figure 1: Comparison between the H1 dσ/dx measurement with predictions for BFKL-LL, BFKL-NLL and DGLAP NLO calculations (see text). S4 and LL BFKL cannot be distinguished on that figure. Following the successful BFKL [2] parametrisation of the forward-jet cross-section dσ/dx at Leading Order (LO) at HERA [3, 4], it is possible to perform a similar study using Next-to-leading (NLL) resummed BFKL...
متن کاملAzimuthal angle decorrelation of Mueller–Navelet jets at NLO
In this contribution we study azimuthal angle decorrelation in inclusive dijet cross sections taking into account the next–to–leading (NLO) corrections to the BFKL kernel while keeping the jet vertices at leading order. We show how the angular decorrelation for jets with a wide relative separation in rapidity largely decreases when the NLO corrections are included.
متن کاملMueller-Navelet Jets at Hadron Colliders
We critically examine the definition of dijet cross sections at large rapidity intervals in hadron–hadron collisions, taking proper account of the various cuts applied in a realistic experimental setup. We argue that the dependence of the cross section on the precise definition of the parton momentum fractions and the presence of an upper bound on the momentum transfer cannot be neglected, and ...
متن کاملAzimuthal 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 afte...
