Description
The parton distribution functions (PDFs) are a fundamental component of hard scattering processes. At leading order, they represent the probability of finding a parton with a momentum fraction x in a hadron target. With the increase in the accuracy of experimental measurements over the last few decades, it has become necessary to enhance the precision of theoretical calculations. To achieve this goal, precise fits of PDFs are indispensable.
In this presentation, I will discuss the LuxQED method for computing the polarized photon PDF. This method allows us to express the photon PDF in terms of the structure functions g1 and g2 The difficulty arises from the necessity of knowing the structure functions across the entire parameter space. I will discuss some models and assumptions available for modeling g1 and g2 in the different regions of the parameter space.
