Leading logarithm calculation of the e+e- -->e+νeūd cross section

We analytically evaluate in the leading logarithm approximation the differential cross section for e⁺e^--->e⁺ν_eūd. We compare our order α⁴α⁰_s leading-log result to the order α⁴α⁰_s exact result obtained from the GRC4F Monte Carlo program. Finally we use the Glück-Reya-Schienbien distribution of partons in a virtual photon, which incorporates both evolution and nonperturbative strong interaction contributions, to obtain better estimates of the differential cross section.
