The Fermilab Program Michael Witherell Users’ meeting June 3, 2004

6/3/042Users' meeting 2004 Fermilab Today ~3000 users do research at Fermilab. We are operating two of the leading programs in particle physics worldwide. The Tevatron program –CDF and D0 experiments –BTeV starting in late 2009 The neutrino program –MiniBooNE with Booster neutrinos –MINOS with NuMI neutrinos Fermilab is also host to –the U.S. program for the LHC accelerator and CMS experiment; –a thriving program in experimental particle astrophysics; and –strong groups in theoretical particle and astrophysics.

6/3/044Users' meeting 2004 Run II is providing new, important physics results. One example: electroweak and Higgs physics Improved top mass measurements are emerging Better top mass and W mass measurements to come Follow the physics news: Every Thursday, a new Fermilab Result of the Week appears in Fermilab Today. CDF/D0 2 fb -1 goal!

6/3/045Users' meeting 2004 Run II Accomplishments in the last year Integrated luminosity delivered to each experiment for physics has gone from ~200 pb -1 to almost 500 pb -1. –Initial luminosity has gone from 4.5x10 31 to 7.3x –The doubling time is still ~1 year. The Recycler has met its requirements for integration into accelerator operations. –Ready to commission “mixed source” operation Physics results on top mass and cross section; jets and dijets; searches for SUSY, leptoquarks, and exotic Higgs particles; W width; B lifetimes and spectroscopy; rare B and D decays; elastic scattering; and more.

6/3/046Users' meeting 2004 Tevatron Operations: FY 2004 Plan and Status Congratulations to the Accelerator Division and all of the people throughout the laboratory for accomplishing this record. Thanks to the members of CDF and D0 collaborations who have contributed to the accelerator effort.

6/3/047Users' meeting 2004 DOE review of Collider Run II So what’s the bottom line? We’re very impressed with the progress in the past seven months. We have increasing confidence that Run II will be successful. We look forward to continued progress toward the Tevatron complex being reliable and well characterized to serve as a platform for the cutting-edge upgrades. But there’s a long way to go in the complex campaign of operations, maintenance, upgrades, R&D, and studies that must succeed if the luminosity goals are to be reached. We see a significant challenge in the installation and successful commissioning of electron cooling in the next 16 months. Keep up the discipline, focus, dedication and good work. We are very encouraged!!!

6/3/048Users' meeting 2004 Projected Integrated Luminosity FY Integrated luminosity will double every year or so for next 4 years

6/3/049Users' meeting 2004 Fermilab and the Large Hadron Collider The U.S. has a big stake in the LHC. –The LHC will make possible the discovery of all the new physics at the TeV scale. Fermilab is lead laboratory for 2 of 3 projects that make this possible. –We manage the US-LHC accelerator project and the LHC Accelerator Research Program (LARP). –We manage the US research program on the large CMS detector project for a group of ~500 U.S. physicists. The LHC research program will be a large activity for Fermilab for the next 20 years.

6/3/0410Users' meeting 2004 MiniBooNE MiniBooNE is a very important experiment. –It has a unique opportunity to confirm or refute the LSND result, which would require a sterile fourth neutrino or something even more novel. –Confirmation would change the worldwide neutrino program. The experiment is running well and the collaboration has made great progress in understanding the detector and backgrounds, and in measuring cross sections. This will be an exciting year ahead.

6/3/0411Users' meeting 2004 Protons to MiniBooNE The Booster has delivered 2.7x10 20 pot, record 7.6x10 18 in one week. We are trying to deliver 5x10 20 as quickly as possible, and then more. Thanks to the MiniBooNE collaboration for their efforts to increase Booster performance.

Funding The science opportunities in High Energy Physics today are limited by funding. Even compared to our neighbors in the Office of Science, HEP has lost about 10%, or $70 million/year, in 5 years. How the funding evolves will determine how much of the future U.S. program can be done.

We are establishing the LHC Physics Center here to make sure that American universities and laboratories to get full scientific benefits from the LHC physics.

6/3/0419Users' meeting 2004 BTeV BTeV will have a very broad particle physics program, including charm physics, but the primary motivation is the search for new physics through CP violation in the B d and B s systems. BTeV represents ~2 orders of magnitude over the present capability in recording tagged B events. P5 in October, 2003: “The strength of the BTeV experiment comes from the combination of its vertex trigger with precision mass measurements for both charged and neutral decay modes and excellent particle identification capabilities.” “P5 supports the construction of BTeV as an important project in the world-wide quark flavor physics area.”

6/3/0420Users' meeting 2004 BTeV in the world HEP program BTeV will be the world’s best experiment in quark flavor physics in the period ~ –It will anchor, with the Fermilab neutrino program, the only HEP program operating at a US accelerator laboratory at that time. –It has gone through the longest and most detailed approval process of any previous experimental facility of its size. –The physics return for the money compares well with anything being done in HEP or in physics.

6/3/0421Users' meeting 2004 Neutrino physics A large part of the world’s neutrino program will use Fermilab accelerators. –The proton plan will include work over the next few years to increase proton intensities. –We will look at what can be done to get even more protons with the present accelerators. –Proton Driver will go beyond that.

6/3/0423Users' meeting 2004 Science First: The Coming Revolution in Particle Physics Something appears to stabilize the Higgs mass. –Supersymmetry? Extra Dimensions? Strong Dynamics? Neutrinos have mass and change flavor. –A new phenomenon at the Grand Unification Scale? B decays may be starting to show puzzles. –Is B →  K S showing signs of new physics? Dark matter must be here somewhere. –Will it show up first in colliders or underground?

6/3/0424Users' meeting 2004 Fermilab in 2020 The overarching vision for Fermilab in 2020 is that it will be the primary site for particle physics accelerators in the U.S. The most favorable outcome for particle physics is that a linear collider is built by an international collaboration of laboratories, within a short distance from here. Because it is not assured that it will be built here, and in a timely way, U.S. particle physics needs to have a plan for the present program to evolve in a way that keeps addressing the most compelling scientific issues.

We want this Center to serve as the intellectual focus for particle astrophysics at Fermilab. –We will locate office space for the various particle astrophysics efforts in one area of Wilson Hall, in order to promote regular communication among the researchers. By taking this step we want to build an intellectual center for particle astrophysics at Fermilab. At the same time, we want to integrate particle astrophysics research more completely into the scientific life of the laboratory.

6/3/0436Users' meeting 2004 Summary Fermilab’s vision for its future is to be the U.S. accelerator laboratory for particle physics, at the forefront of the coming scientific revolution. The laboratory will be the home –for accelerator-based particle physics in the U.S. –for American physicists working abroad at the world’s highest energy accelerator –for some of the most far-reaching experiments at the boundary of particle physics and cosmology. The discoveries of the coming decade will significantly clarify the detailed picture of what U.S. particle physics will look like in twenty years.
