LEPTON PAIR PRODUCTION - WHERE THE SIMPLE DRELL-YAN PICTURE BREAKS DOWN

Abstract:

We point out that over an experimentally important kinematic region lepton pair production arises from the annihilation of a quark and antiquark within the same hadron. This renders incorrect the conventional extraction of structure functions from data in this region. Instead it now becomes possible to obtain information on the correlation between a quark and antiquark within the same proton. We carefully quantify this kinematic region of interest and illustrate it with a discussion of the va...
