“…It was demonstrated there that the NLLx correction to the ∆φ independent pedestal is a large one (a factor 2 to 3). However, the NLLx contribution to the collimated cos(∆φ) and cos(2∆φ) moments (as also confirmed in [35]), which are the quantities of interest here, is 10-30%; further, we expect our inclusion of running coupling in Eq. (6) will potentially account for a good fraction of this correction.…”

We perform a detailed comparison of long range rapidity correlations in the Color Glass Condensate framework to high multiplicity di-hadron data in proton-proton and proton-lead collisions from the CMS, ALICE and ATLAS experiments at the LHC. The overall good agreement thus far of the non-trivial systematics of theory with data is strongly suggestive of gluon saturation and the presence of subtle quantum interference effects between rapidity separated gluons. In particular, the yield of pairs collimated in their relative azimuthal angle ∆φ ∼ 0, is sensitive to the shape of unintegrated gluon distributions in the hadrons that are renormalization group evolved in rapidity from the beam rapidities to those of the measured hadrons. We present estimates for the collimated di-hadron yield expected in central deuteron-gold collisions at RHIC.

“…The expression for the "jet vertices" was first obtained with NLO accuracy in [16,17], a result later confirmed in [18]. A simpler expression, more practical for numerical purposes, was obtained in [19] within the so-called "smallcone" approximation (SCA) [20][21][22], i.e.…”

We study the production of Mueller-Navelet jets at 13 TeV LHC, within collinear factorization and including the BFKL resummation of energy logarithms in the nextto-leading approximation. We calculate several azimuthal correlations for different values of the rapidity separation Y between the two jets and evaluate the effect of excluding those events where, for a given Y , one of the two jets is produced in the central region.

“…In [37], we presented a first phenomenological analysis at LLA for the respective hadronic-level ratios R M N P Q . These were obtained after using collinear factorization to produce the two most forward/backward jets and convoluting the partonic differential cross section, which follows the BFKL dynamics, with collinear parton distribution functions included in the forward "jet vertex" [41,42,43,44,45,46,47]. In addition, the two MuellerNavelet jet-vertices were linked with the centrally produced jet via two BFKL gluon Green functions.…”

Stability of azimuthal-angle observables under higher order corrections in inclusive three-jet production

Recently, a new family of observables consisting of azimuthal-angle generalised ratios was proposed in a kinematical setup that resembles the usual Mueller-Navelet jets but with an additional tagged jet in the central region of rapidity. Non-tagged minijet activity between the three jets can affect significantly the azimuthal angle orientation of the jets and is accounted for by the introduction of two BFKL gluon Green functions. Here, we calculate the, presumably, most relevant higher order corrections to the observables by now convoluting the three leading-order jet vertices with two gluon Green functions at next-to-leading logarithmic approximation. The corrections appear to be mostly moderate giving us confidence that the recently proposed observables are actually an excellent way to probe the BFKL dynamics at the LHC. Furthermore, we allow for the jets to take values in different rapidity bins in various configurations such that a comparison between our predictions and the experimental data is a straightforward task. * 'La Caixa'-Severo Ochoa Scholar.
