It was a great pleasure for us to host the 22nd Physics in Collision (PIC) Con- ference this year. The PIC conference series was established in 1981, and conferences have been held annually at various locations in Europe, North America and Asia. This is a three-day plenary conference where invited speakers review and update key topics in elementary particle physics, with the aim of encouraging informal discussions on experi- mental results and their implications. The scope of the conference series has broadened progressively through its history. For most recent PIC conferences, a poster session has also been included to further promote participation. The broad range of topics and active participation have been characteristic of the PIC series and have allowed the opportunity for an overview of subjects outside one’s specialized field and direct communication with experts in those fields. This year’s PIC conference was held at the new Teaching Center at the Science and Engineering Quad on the Stanford University campus, June 20-22, 2002, jointly or- ganized by the Stanford Physics Department and the Stanford Linear Accelerator Center (SLAC). There were 92 registered participants at the conference. We enjoyed 26 review talks presented by invited speakers and 12 accepted posters displayed at the poster session. We are very grateful to the International Advisory Committee and our Local Organizing Committee members for their valuable help, especially on the scientific program. We thank the invited speakers for the excellent reviews they presented and the authors of the high quality posters put on display. As part of the conference program, we also had interesting laboratory visits of Gravity Probe B, Satellite Test of the Equivalence Principle (STEP), Cryogenic Dark Matter Search (CDMS) and Enriched Xenon Observatory (EXO) on the

v Stanford campus, as well as a tour of BaBar and the accelerator/experiment complex at SLAC. Among the many who contributed to the success of the conference, we would particularly like to thank SLAC technical publications, SLAC computing services, our dili- gent scientific secretaries and tour guides, and Stanford event services. We are especially grateful to Maura Chatwell and her conference organization crew who took care of the many details to make the conference work as a whole. After our very positive experience hosting this year’s conference, we look forward to the continued success of the PIC series in the years to come.
