Evaluating the double parton scattering contribution to Mueller-Navelet jets production at the LHC

Abstract

Abstract:We propose a model to study the importance of double parton scattering (DPS) in Mueller-Navelet jets production at the LHC which is consistent with the BFKL framework used to compute the single parton scattering contribution to this process. We study this model in kinematics corresponding to existing and possible future measurements at the LHC and estimate the importance of this DPS contribution on relevant observables for this process, namely the cross section and the azimuthal correlation of the jets.

Dihadron production at the LHC: full next-to-leading BFKL calculation

“…The double-parton scattering contribution to the Mueller-Navelet jet production was considered in Refs. [31] and [72], using different approaches. It would be very interesting if similar estimates were done also for the case of dihadron production.…”

“…A large number of numerical analyses [23][24][25][26][27][28][29][30][31][32][33][34][35] has appeared so far, which have been devoted to NLA BFKL predictions for the Mueller-Navelet jet production process. All these studies are involved in calculating cross sections and azimuthal angle correlations [36,37] between the two measured jets, i.e.…”

High-energy resummation in heavy-quark pair hadroproduction

“…Pursuing the goal to get a more exhaustive comprehension of this high-energy regime, a significant range of semi-hard reactions (see Ref. [21] for applications) has been proposed so far: the diffractive leptoproduction of one [22][23][24] or two light vector mesons [25][26][27][28], the inclusive hadroproduction of two jets featuring large transverse momenta and well separated in rapidity (Mueller-Navelet channel [29]), for which several phenomenological studies have appeared so far [30][31][32][33][34][35][36][37][38][39][40][41][42][43][44], the inclusive detection of two light-charged rapidity-separated hadrons [45][46][47], three-and four-jet hadroproduction [48][49][50][51][52][53][54][55][56], J/Ψjet [57], hadron-jet [58-60] and forward Drell-Yan dilepton production [61][62][63] with a possible backward-jet tag [64,65].…”

Dihadron production at LHC: BFKL predictions for cross sections and azimuthal correlations

“…For this reaction, the BFKL resummation with NLA accuracy relies on the combination of two ingredients: the NLA Green's function of the BFKL equation [3,4] and the NLA jet vertices [5][6][7][8][9]. In [10][11][12][13][14][15][16][17][18][19][20][21] NLA BFKL predictions of cross sections and azimuthal angle correlations for the Mueller-Navelet jet process, observables earlier proposed in [22][23][24][25], were given, showing a very good agreement with experimental data at the LHC [26]. In order to further and deeply probe the dynamical mechanisms behind partonic interactions in the Regge limit, s |t|, some other observables, sensitive to the BFKL dynamics, should be considered in the context of the LHC physics program.…”
