Dear Colleague —

The HEPAP subpanel on long range planning has completed the first phase of its information gathering process. During the past four months, the panel has heard a series of presentations in Gaithersburg and at Brookhaven, Fermilab and SLAC. The slides are available on the panel's web site, at

http://hepserve.fnal.gov:8080/doe-hep/lrp_panel/index.html.

The next phase will begin with the Snowmass Workshop in July. As part of that process, the panel would like to invite written comments from the community. To be most helpful, letters should address the issues raised by our charge. In particular, we are grappling with the following questions:

• What is the scope of particle physics?
• What are the most important scientific questions facing the field?
• What tools and approaches are required to address these questions?
• Does the science require a major new facility?
• If so, should the US bid to host it? What are the advantages and disadvantages? How might the disadvantages be mitigated?
• What are the essential elements of a successful international partnership? How should it be implemented?
• What is the role of astroparticle physics and cosmology in the field?
• What is the relation between particle physics and other fields of science and technology?
• What are the important issues facing university groups? What is their role in the future evolution of the field?
• What are the most pressing R&D goals for accelerators and detectors?
• What does particle physics offer to society?
• What are the contributions of our field to other areas of science and technology?
• How do accelerator and detector R&D benefit society?
• What should the particle physics community do differently?

We welcome your thoughts on these questions and the issues before us, as well as any other comments you might have. Please send your comments to panel@pha.jhu.edu. Unless you request otherwise, your letter will be posted on our web site.

Thank you for your help in this important endeavor.
