Leading logarithm calculation of the e+ e- -> e+ e u d cross section
Abstract
We analytically evaluate in the leading logarithm approximation the differential cross section for e+ e- -> e+ e u d. We compare our order α4 αs0 leading-log result to the order α4 αs0 exact result obtained from the GRC4F Monte Carlo program. Finally we use the Gluck, 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.
