Тема семинара: «QED NLO parton distribution functions»

Докладчики: Андрей Арбузов, Ульяна Возная

Аннотация:

Unpolarized parton distribution functions are calculated within the NLO approximation in QED. The iterative procedure of solving QED DGLAP equations is described. Features of factorization of large logarithmic corrections in QED are discussed. The results are applied for description of initial state radiative corrections to a general electron-positron annihilation process. Comparisons with the formulae known in the literature are performed. The results are relevant for high-precision experiments in high-energy physics.
