摘要：

High-Q(2) NC and CC cross sections as measured at HERA can give information on two distinct areas of current interest. Firstly, supposing that all the electroweak parameters are well known, these cross sections may be used to give information on parton distribution functions (PDFs) in the new kinematic regime at high x and high Q(2). Secondly, supposing that PDFs are well known after evolution in Q(2) from the kinematic regime where they are already measured, these cross sections may be used to give information on electroweak parameters in a process where the exchanged boson is 'spacelike' rather than 'timelike'. WG1 addressed itself to clarifying the limits of our present and possible future knowledge on both these points.
