Abstract
We study, within QCD collinear factorization and including BFKL resummation at the next-to-leading order, the production of Mueller-Navelet jets at LHC with center-of-mass energy of 7 TeV. The adopted jet vertices are calculated in the approximation of small aperture of the jet cone in the pseudorapidity-azimuthal angle plane. We consider several representations of the dijet cross section, differing only beyond the next-to-leading order, to calculate a few observables related with this process. We use various methods of optimization to fix the energy scales entering the perturbative calculation and compare thereafter our results with the experimental data from the CMS collaboration.
Highlights
We specified that the coefficients C0, C1, C2 and C3 given in Table 7 are measured in nb
The coefficients C0 and C1 given in Table 6 are measured in nb
We observe that the lower limits in the integrations over y1 and y2 of Eq (13) were reported as y1,min = y2,min = 0, while the correct values, as used in the numerical analyses, are instead y1,min = y2,min = −4.7
Summary
We specified that the coefficients C0, C1, C2 and C3 given in Table 7 are measured in nb.
