The RSVP Project: Fundamental Physics at the Sensitivity Frontier

1. The RSVP Project:Fundamental Physics at the Sensitivity Frontier • RSVP consists of two particle physics experiments that have the potential to profoundly change our understanding of the basic constituents of matter and the forces by which they interact: • MECO is a search for conversion of muons to electrons.Goal is to understand better the family structure of leptons, why there exist 2 extra copies of particles that make up the matter around us. • KOPIO is a search for decay of a neutral kaon to a neutralpion, a neutrino and an anti-neutrino.The goal is to understand better CP violation, which is requiredto produce a Universe containing matter rather than a mixture of matter and anti-matter. Meeting with Congressman Miller’s Staff

2. Who are the RSVP Participants? • Sponsoring agency – • National Science Foundation, Division of Mathematical and Physical Sciences, MREFC Program. • NSF has been singled out as an agency • that is efficiently managed. • Host Laboratory – • Brookhaven National Laboratory, Operated by Brookhaven Science Associates for the Department of Energy, Office of Science, Division of Nuclear Physics • Breaking New Ground in Inter-Agency Cooperation MECO and KOPIO Scientific Collaborations – Boston University Brookhaven National Laboratory University of California, Irvine University of Cincinnati University of Houston University of Massachusetts, Amherst SUNY, Stony Brook University of New Mexico New York University University of Pennsylvania Syracuse University University of Virginia Virginia Polytechnic Institute and State University College of William and Mary Yale University International Collaborators – Canada Italy Japan Russia Switzerland Meeting with Congressman Miller’s Staff

7. RSVP Has Passed Scientific Scrutiny at All Levels • RSVP experiments were reviewed and approved on science objectivesby peer review panel at Brookhaven National Laboratory (1997). • RSVP was very strongly supported by NSF appointed peer review panel (1999): A positive result from that experiment would have a profound effect on our understanding of the fundamental constituents of matter and of the forces that govern their behavior. • RSVP has received high marks in many NSF cost, schedule and management reviews, both internal and external (1999-2001): RSVP was critically reviewed internally at NSF by senior management from all of the NSF Directorates, resulting in broad, strong support for going forward.* • RSVP has been approved by the National Science Board (October 2000):The National Science Board reviewed the case for RSVP and approved it “for inclusion in the FY 2002 or later budget.” * • RSVP continues to have the strong backing of the NSF: RSVP is now the highest priority construction project from the Directorate of Mathematical and Physical Sciences.* • *letter from Robert Eisenstein, NSF Assistant Director Meeting with Congressman Miller’s Staff

8. What is the California Stake in this Project? • The MECO collaboration was initiated and is led by UCI scientists. • The MECO project will be funded through UCI. • National Laboratories in California have expertise useful to the project: • Accelerator technology (LLNL and LANL) • Superconducting magnet technology (LLNL) • Large project experience • California industry will strongly compete for many parts of the project: • $30M superconducting magnets will be built at a company like General Atomics • Many high tech companies in computing, electronics, cryogenics, engineering, precision machining, etc. • The MECO experiment will contribute to training students and postdocs;an outreach program for area high school and middle school teachers is planned • Scientific results will contribute to the reputation of the University of California. Meeting with Congressman Miller’s Staff

9. What are the Financial Resources Required for RSVP? Construction project cost of approximately $120M over 5 yearsSource: NSF MREFC Program Incremental operating expenses at the collaborating institutions and Laboratory of about $12M per year for 3-4 yearsSource: NSF Division of MPS Substantial resources are available from international collaborating institutions contingent on U.S. funding. Meeting with Congressman Miller’s Staff

10. Why Should the Country Fund RSVP Now? • Intellectual pursuits, including attempts to understand how the universe works, are one of the underpinnings of our society. • Historically, fundamental research in the physical sciences has produced enormous collateral technological benefits that contribute in many areas;one example is superconducting magnet technology and MRI machines. • The United States has the intellectual and financial resources to pursue technologically challenging problems in a way that few other countries do. • Scientific progress is made incrementally; a long range vision and commitment is needed to maintain progress; payout is beyond the horizon for private industry. • RSVP can very efficiently use an infrastructure that exists now. Both the physical infrastructure and the personnel involved have limited productive lifetime. • Funding projects when they are ready ultimately reduces the cost.
