Prospectus

The primary goals of our subgroup are to address:
1. the experimental and theoretical issues related to the measurement/extraction of structure functions/PDFs, mainly for input to other physics; and
2. the use of structure functions themselves to extract physics (QCD tests, evolution issues, saturation, BFKL, Pomeron structure, etc.).

One tangible result of this group will be a report to be published with the proceedings. Presumably, this should include

1. a compilation of the present status of structure functions, and
2. a progress report of new projects initiated at this workshop.

The first item requires a review of the present data and literature, appending a critical assessment regarding the proposed machine parameters. Here, we can make use of previous work, but the material will have to be reorganized. In this process, we may uncover unresolved issues and new directions, and this should stimulate new collaborative projects for the second item.

Participation in the Structure Functions Subgroup is not an exclusive proposition. We plan to collaborate coherently with other subgroups where cooperation is natural, and there will be sufficient flexibility for members to work with more than one group.
