Description
QED structure and fragmentation functions are systematically derived within the next-to-leading order approximation. DGLAP evolution equations are solved by iterations. Perturbative results are shown for electron parton distribution functions up to O(\alpha^3L^2), where L=\ln(\mu^2/m^e^2) is the large logarithm and \mu is the factorization energy scale. The results are relevant for the present and future experiments at electron-positron colliders.
