    QCD Resummation in Hard Diffractive Dijet Production at the Electron-Ion Collider

    Yoshitaka Hatta🇺🇸 · Niklas Mueller🇺🇸 · Takahiro Ueda🇯🇵 · Feng Yuan🇺🇸

    Diffractive dijet production at the electron-ion collider (EIC) has been proposed to study the gluon Wigner distribution at small-. We investigate the soft gluon radiation associated with the final state jets and an all order resummation formula is derived. We show that the soft gluon resummation plays an important role to describe E791 data on -induced diffractive dijet production at Fermilab. Predictions for the EIC are presented, and we emphasize that the soft gluon resummation is an important aspect to explore the nucleon/nucleus tomography through these processes.

    Studying transverse momentum distributions with jets at NLL

    Daniel Gutierrez-Reyes🇪🇸 · Ignazio Scimemi🇪🇸 · Wouter J. Waalewijn🇳🇱 · Lorenzo Zoppi🇳🇱

    Semi-inclusive deep inelastic scattering (SIDIS) is a promising channel for the extraction of transverse momentum dependent distributions at future colliders. In this context, we recently developed a framework that uses jets (instead of single hadrons) to achieve reduced sensitivity to final-state non-perturbative effects. A suitable non-standard jet definition allows us to apply the factorization formulas valid for hadrons to jets of arbitrary size, by just replacing fragmentation functions with the jet functions we computed. Besides presenting the framework, we will show numerical predictions at NLL accuracy.

    Cold QCD at finite isospin density: confronting effective models with recent lattice data

    Sidney S. Avancini🇧🇷 · Aritra Bandyopadhyay🇧🇷 · Dyana C. Duarte🇧🇷 · Ricardo L. S. Farias🇧🇷

    We compute the QCD equation of state for zero temperature and finite isospin density within the Nambu-Jona-Lasinio model in the mean field approximation, motivated by the recently obtained Lattice QCD results for a new class of compact stars: pion stars. We have considered both the commonly used Traditional cutoff Regularization Scheme and the Medium Separation Scheme, where in the latter purely vacuum contributions are separated in such a way that one is left with ultraviolet divergent momentum integrals depending only on vacuum quantities. We have also compared our results with the recent results from Lattice QCD and Chiral Perturbation Theory.

    Out of equilibrium chiral magnetic effect and momentum relaxation in holography

    Jorge Fernández-Pendás🇪🇸 · Karl Landsteiner🇪🇸

    We compute anomalous transport phenomena sourced by vector and axial magnetic fields in out of equilibrium setups produced by Vaidya background metrics in holography. We use generalized Vaidya metrics that include momentum relaxation induced by massless scalar fields. While the background metric and gauge field show formally instantaneous thermalization the chiral magnetic effect has significantly large equilibration times. We study how the equilibration of the chiral magnetic effect depends on the length of the Vaidya quench and the momentum relaxation parameter. These results shed some light on aspects of the chiral magnetic effect in out of equilibrium situations as the quark gluon plasma produced in heavy ion collisions.
