New 5-flavor LO analysis and parametrization of parton distributions in the real photon

New, radiatively generated, leading order (LO) quark (u,d,s,c,b) and gluon densities in a real, unpolarized photon are presented. We perform a global 3-parameter fit, based on LO Dokshitzer-Gribov-Lipatov-Altarelli-Parisi evolution equations, to all available data for the structure function F2gamma(...
