Forward $J/\psi$ and very backward jet inclusive production at the LHC
In the spirit of Mueller-Navelet dijet production, we propose and study the inclusive production of a forward $J/\psi$ and a very backward jet at the LHC as an observable to reveal high-energy resummation effects \`a la BFKL. We obtain several predictions, which are based on the various mechanisms discussed in the literature to describe the production of the $J/\psi$, namely, NRQCD singlet and octet contributions, and the color evaporation model.
Double scattering contribution to small-x processes: Mueller-Navelet jets at the LHC
We study the importance of double parton scattering (DPS) in Mueller-Navelet jets production at the LHC. We evaluate this contribution in kinematics corresponding to existing and possible future measurements at the LHC, for the cross section and the azimuthal correlation of the jets.
High-energy resummation effects in Mueller-Navelet jets production at the LHC
We summarize recent developments in the study of high-energy resummation effects in Mueller-Navelet jets production at the LHC and discuss possible relations with multiparton interactions.
Mueller–Navelet Jets at the LHC
We report on our NLL BFKL studies of Mueller-Navelet jets. We first perform a complete NLL BFKL analysis supplemented by a BLM renormalization scale fixing procedure, which is successfully compared with recent CMS data. Second, we argue for the need of a measurement of an asymmetric jet configuration in order to perform a valuable comparison with fixed order approaches. Third, we predict that the energy-momentum violation is rather tiny in the NLL BFKL approach, for an asymmetric jet configuration. Finally, we argue that the double parton scattering contribution is negligible in the kinematics of actual CMS measurements.
Probing BFKL dynamics in Mueller-Navelet jet production at the LHC
We review the results of our studies on the production of two jets with a large interval of rapidity at hadron colliders, which was proposed by Mueller and Navelet as a possible test of the high energy dynamics of QCD, within the next-to-leading logarithm framework. The application of the Brodsky-Lepage-Mackenzie procedure to fix the renormalization scale leads to a very good description of the available CMS data at the LHC for the azimuthal correlations of the jets. We show that the inclusion of next-to-leading order corrections to the jet vertex significantly reduces the importance of energy-momentum non-conservation which is inherent to the BFKL approach, for an asymmetric jet configurat…
Production of a forward J/ψ and a backward jet at LHC
We study the production at the LHC of a forward J/ψ meson and a backward jet with a large rapidity separation using the BFKL formalism. We give predictions for both the Non Relativistic QCD (NRQCD) approach to charmonium production and the Color Evaporation Model. In NRQCD, we find that the 3S18 part of the onium wavefunction is completely dominating the process, which makes the presented study a good probe for this color octet contribution. peerReviewed
The Large Hadron–Electron Collider at the HL-LHC
The Large Hadron-Electron Collider (LHeC) is designed to move the field of deep inelastic scattering (DIS) to the energy and intensity frontier of particle physics. Exploiting energy-recovery technology, it collides a novel, intense electron beam with a proton or ion beam from the High-Luminosity Large Hadron Collider (HL-LHC). The accelerator and interaction region are designed for concurrent electron-proton and proton-proton operations. This report represents an update to the LHeC's conceptual design report (CDR), published in 2012. It comprises new results on the parton structure of the proton and heavier nuclei, QCD dynamics, and electroweak and top-quark physics. It is shown how the LH…
Evaluating the double parton scattering contribution to Mueller-Navelet jets production at the LHC
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.
