Unpolarized QED Parton Distribution Functions in NLO / A.B.Arbuzov, U.E.Voznaya // Journal of Physics G [Electronic resource]. – 2023. – Vol. 50, No. 12. – P. 125004. – URL: https://doi.org/10.1088/1361-6471/acff7b.

Perturbative solutions for unpolarized QED parton distribution and fragmentation functions are presented explicitly in the next-to-leading logarithmic approximation. The scheme of iterative solution of QED evolution equations is described in detail. Terms up to O(*a*3 L*2) are calculated analytically, where L=ln(*m*2&sub(F)/m*2&sub(e)) is the large logarithm which depends on the factorization energy scale μ&sub(F) ≫ m&sub(e). The results are process independent and relevant for future high-precision experiments.
