A major pillar of the scientific program of the future Electron-Ion Collider and upcoming upgrades for the Large Hadron Collider is the discovery and characterization of a new regime of nuclear matter, known as color glass condensate (CGC), dominated by a highly dense and saturated system of gluons. Predictions from the CGC effective theory have been confronted with experimental data from HERA, RHIC, and the LHC, where suggestive but not definitive signatures of gluon saturation have been observed. In this seminar, I will review the state-of-the-art precision calculations for various processes in the CGC/saturation formalism. I will focus on our recent work on double and single semi-inclusive jet production in deep inelastic scattering, which reveals the need for joint high energy and soft gluon resummation and their interplay to accurately uncover the observable signatures of saturation phenomena in existing and future colliders.

Farid Salazar was born and raised in Lima, Peru. He earned his Ph.D. in Physics from Stony Brook University in 2021, while he conducted research with the Nuclear Theory Group at Brookhaven National Laboratory (BNL). Afterwards, Farid held postdoctoral positions at UCLA, UC Berkeley, and Lawrence Berkeley National Laboratory. In 2023, he joined the Institute for Nuclear Theory at the University of Washington as a Research Assistant Professor (Junior Fellow). He will join the Physics faculty at Temple University with a joint appointment with the RIKEN Brookhaven Research Center at BNL in January 2025.
Farid's research explores hadronic and nuclear matter in high-energy collisions. His work centers on advancing the Color Glass Condensate (CGC), an effective field theory (EFT) of high-energy Quantum Chromodynamics, which describes a universal form of matter dominated by a highly dense and saturated system of gluons inside hadronic and nuclear matter. His recent focus is elucidating the relation between the CGC EFT and the transverse-momentum-dependent factorization framework and studying exclusive processes for imaging nuclei in ultra-peripheral heavy-ion collisions.
