    Title: e a collisions at the large hadronelectron collider
    Author: Armesto, Néstor
    Subject: Physics;
    Description: I show the possibilities for electronion studies offered by the proposed electronhadron collider at CERN, the Large Hadronelectron Collider. I first focus on small- x aspects: inclusive measurements and the determination of parton densities, and diffraction. I end by discussing some possibilities for final state studies.

    Title: Kinematic biases on centrality selection of jet events in pPb collisions at the LHC
    Author: Armesto, Nestor
    Contributor: Armesto, Nestor (pacrepositoryorg)
    Subject: Collaboration ; Collisions ; Large Hadron Collider ; Solenoids ; Jets ; Cooperation ; Nucleons ; Computer Simulation ; Energy Conservation
    Description: Centrality selection has been observed to have a large effect on jet observables in pPb collisions at the Large Hadron Collider, stronger than that predicted by the nuclear modification of parton densities. We study to which extent simple considerations of energy-momentum conservation between the hard process and the underlying event affect jets observables in such collisions. We develop a simplistic approach that considers first the production of jets in a pp collision as described by PYTHIA. From each pp collision, the value of the energy of the parton from the proton participating in the hard scattering is extracted. Then, the underlying event is generated simulating a pPb collision through HIJING, but with the energy of the proton decreased according to the value extracted in the previous step, and both collisions are superimposed. This model is able to capture the bulk of the centrality effect for central to semicentral collisions, for the two available sets of data: dijets from the...

    Title: Diffractive photoproduction of vector mesons at the LHC
    Author: Armesto, Néstor; Rezaeian, Amir
    Contributor: Rezaeian, Amir (pacrepositoryorg)
    Subject: Photoproduction ; Vector Mesons ; Mesons ; Dipoles ; Saturation
    Description: We confront saturation-based results for diffractive \(\psi(2s)\) and \(\rho\) production at HERA and \(J/\psi\) photoproduction with all available data including recent ones from HERA, ALICE and LHCb, finding a good agreement. We show that the \(t\)-distribution of differential cross-section of photoproduction of vector mesons offers a unique opportunity to discriminate among saturation and non-saturation models. This is due to emergence of a pronounced dip (or multiple dips) in the \(t\)-distribution of diffractive photoproduction of vector mesons at relatively large, but potentially accessible \(|t|\) that can be traced back to the unitarity features of colour dipole amplitude in the saturation regime. We provide various predictions for exclusive (photo)-production of different vector mesons including the ratio of \(\psi(2s)/J/\psi\) at HERA, the LHC and at future colliders.
