Physics Seminar: Wednesday April 5th ---Small-x evolution of flavor-singlet helicity distributions by : Small-x evolution of flavor-singlet helicity distributions

Hi Everyone!


Time: 04/05/2023, Wednesday,  2pm - 3pm.
Location: Room M2035.

Speaker: Florian COUGOULIC (IGFAE, Spain)
Title: Small-x evolution of flavor-singlet helicity distributions
Abstract: One of the main goals of hadronic physics is to understand the spin of the proton. It is one of the topics that will be experimentally addressed at the EIC. Understanding how the proton spin is made up of its constituents, quark or gluon spin and orbital angular momentum, requires theoretical inputs at Bjorken-x values below experimentally achievable ones.
In this presentation, I will introduce the small-x formalism used to describe unpolarized observables. Then I will describe our approach to the polarized observables by focusing on flavor-singlet helicity distributions. I will finally underline how our recent work resolved a previous disagreement with pioneering works by Bartels and al. for the intercept of the flavor-singlet distributions small-x asymptotic, in the limit of large number of color.
