Zapraszamy na seminarium 19.12.2023

Dear All,


We have the pleasure of inviting you to the Particle Theory Seminar on Tuesday, December 19  at 12:15, which will be given by


Aleksander Kusina (IFJ PAN)




„Short range correlations and high-x structure of nuclei".




The structure of nucleons as well as nuclei at large longitudinal momenta, x, is crucial for understanding QCD confinement or for explaining the origins of the nuclear EMC effect. Parton distribution functions (PDFs), which describe the longitudinal structure of hadrons or nuclei, are typically determined in global analysis of experimental data. Unfortunately, the high-x region is hard to determine due to different theoretical effects that enter in this challenging region. In this talk I present a recent analysis where we have accounted for them and determined nuclear PDFs using high-x data from JLAB experiments. I also present preliminary results of a related study where such analysis was preformed in a framework inspired by short-range correlation (SRC) models which are used to explain nuclear EMC effect. It showed remarkable agreement with the traditional purely phenomenological fitting framework as well as some low energy data and nuclear calculations.


The speaker will be on-site, local participants are invited to meet in the seminar room D-2-02.
