1 High Energy Physics at the University of Wisconsin Madison This proposal is to conduct research from FY08 through FY10 on the experimental and theoretical frontiers of particle physics. The CDF Task E of Profs. Carlsmith, Herndon and Pondrom will search for the Higgs boson at the Tevatron where sensitivities are approaching the three times the Standard Model (SM) cross section. They will study B s oscillations, rare B- decays, and high-mass jets. The group has leading responsibilities in the B-Physics and Higgs physics groups as well as responsibility for the CDF intermediate angle muon system. After BaBar discovered CP violation phenomena in the B meson sector, Task C of Profs. Dasu and Prepost will work to firmly establish the CKM quark mixing formalism in the Standard Model (SM) and to determine very tight constraints on physics beyond the SM. Task C also has a significant involvement in detector and accelerator R&D for the ILC. The ZEUS Task B of Prof. Smith will complete studies of QCD at HERA and exploring jet and QCD evolution physics with direct bearing on LHC measurements. Prof. Heeger s task will work on construction of the Daya Bay Reactor Antineutrino Experiment and start in 2009 to measure the electron neutrino coupling to the third mass eigenstate and the corresponding unknown neutrino mixing angle θ 13. The ATLAS Task H of Profs. Mellado, Pan and Wu and CMS Task T of Profs. Carlsmith, Dasu, Herndon and Smith are completing 15 years of studies, design, construction, installation, commissioning and now maintenance and operations of major components of their detectors for the LHC, as well as simulation and computing facilities for physics analysis. The ATLAS group has leading roles in the silicon and pixel readout driver, high level trigger (HLT), Higgs physics studies and software and computing. The CMS group has leading responsibilities in the Trigger (Level-1 and HLT) and Endcap Muon systems, physics coordination, software and computing. Both groups are looking forward to discoveries such as the Higgs boson, supersymmetry, exotic particles, extra dimensions or whatever else emerges in this new regime. They are also working on the simulation and detector upgrade program for the Super LHC. The phenomenology Task G of Profs. Barger, Everett, Halzen, Han and Petriello will apply its internationally recognized expertise on calculations of new physics models and SM backgrounds to interpret the new data from the experimental frontier. With the imminent turn-on of the LHC, collider physics phenomenology is a central focus and this group proposes to perform these important calculations and the training of students and postdocs to perform these calculations in the future. The QCD theory Task Q of Prof. Petriello will develop novel methods for ultra-precise calculations in quantum field theory and applying them to Tevatron and LHC phenomenology. The theoretical cosmology Task J of Prof. Chung will study the implications of dark matter and dark energy theories for observations at colliders and particle astrophysics. Prof. Chung will study the consequences of his new field theories for general relativity, cosmology - 1 -

2 and particle physics and exploring electroweak baryogenesis. The String Theory Task D of Profs. Hashimoto, Klemm, and Shiu will investigate the extensive range of topics in string theory ranging from its mathematical formulations to phenomenological applications. Their research aims to provide new insights and a foundation for studying quantum gravity, strong interaction physics, physics beyond the Standard Model, and the early universe. The University of Wisconsin has made an extraordinary investment in the HEP program. In the past two years, we have added 5 new junior faculty members. In 2006 we hired Bruce Mellado, on ATLAS who is a convener of the Higgs and Standard Model Analysis Forum for US ATLAS, Lisa Everett who has distinguished herself in the connections between string theory and LHC phenomenology and Karsten Heeger, who is US antineutrino detector manager for Daya Bay. In 2005, we hired Matt Herndon, who was the CDF B-physics co-convenor in and is now the CDF Higgs search co-convenor and has joined CMS and Frank Petriello (OJI in 2007 Task Q) who joined our phenomenology group and is an expert on QCD physics and the LHC. We made these faculty hires after hiring 4 (3 junior) other HEP faculty in the recent past, String Theorists Aki Hashimoto and Albrecht Klemm (senior hire) and Theoretical Cosmologist Dan Chung (OJI in 2005 Task J) were hired in String Theorist Gary Shiu (NSF Career in 2004) was hired in In the 3-year time-span of this proposal the focus of experimental collider physics will change from HERA, the SLAC B-factory and the Tevatron to the LHC and R&D for the SLHC and the ILC. We are eager to embrace the challenges and opportunities of this new world and believe that our plans align well with the National program priorities stated by the NAS EPP2010 report, P5 and HEPAP. Anticipating the end of HERA-II in June 2007, Prof. Smith proposed to redirect Task B funding for personnel supporting the ZEUS trigger and QCD physics analysis to Task T on CMS, completing this process during FY08. However, while the awarded funding to Task B was reduced, it was not awarded to Task T. The Babar Task C of Profs. Dasu and Prepost is migrating resources to work on ILC R&D and CMS computing and physics. R. Prepost leads a long-term program for the development and design of the ILC polarized source and Senior Scientist H. Band is the Working Group leader for the muon system in the silicon detector (SiD) design concept. S. Dasu is setting up a CMS physics analysis center based on the Wisconsin grid computing facilities. The CDF Task E of Profs. Carlsmith, Herndon and Pondrom is migrating resources to the CMS Endcap Muon system alignment, tracking and Higgs physics searches. The group s experience with the CDF Intermediate Muon System and CDF tracking are being put to use on CMS muon system alignment and tracking. Prof. Herndon s leadership of the CDF Higgs group until 2008 is an important asset for the CMS Higgs search. The UW HEP group is active in education, having graduated 27 Ph.D. students since January 2004, 20 in experiment and 7 in theory. HEP members collaborate with each other. String Theory, Theoretical Cosmology, and Phenomenology all work closely together. Phenomenologists work with the members of the experimental groups on physics measurements - 2 -

3 and simulations. The experimental groups collaborate with each other. The ATLAS and CMS groups have collaborated extensively together on computing with members of the UW Computer Science Dept. Condor Team and created a computing resource at Wisconsin for LHC physics simulations that has produced the most events world-wide. We are actively involved in interdisciplinary computing research with biologists, geneticists, chemists, engineers, medical doctors and other scientists on campus as well as IceCube. The UW has contributed hundreds of thousands of dollars in support of this computing, which now provides us with unparalleled facilities for physics analysis and simulations. Leveraging the shared resource of the Physical Sciences Laboratory, we have successfully executed such projects as the design and construction of state of the art electronics for collider detector triggers, the endcap steel and considerable infrastructure for CMS and propose to use these resources for future detector construction and upgrades, such as the central target vessels for Daya Bay and their instrumentation. The Wisconsin HEP group has a more than 50-year successful history and proposes to push the research frontiers and undertake new endeavors with our new junior faculty. The following tables show the last four years funding history and the request for FY08 and a summary of the three year funding request contained in this proposal: The individual task budgets and justifications are included in each task section. Tasks S & P, the Common Task and the Data Analysis Facility, were in 2005 redistributed across most tasks and are called out as the Admin column in the Task budgets. This table keeps them separate so that the Research dollars can be evaluated more clearly. The table illustrates that while our responsibilities have increased in many projects and new physics data is at our doorstep we have been losing the base funding for physicist support needed to fully exploit the upcoming opportunities.

In 2006 the UW picked up 1/2 the cost of A. Lefkow, Program Manager. A. Lefkow is now responsible for all grants in the Physics Department except Plasma Physics. In 2007 the UW also picked up 1/2 the cost of S. Rader, Systems Administrator. This modification is discussed in the Task T budget narrative. Computing Infrastructure: We make a computing infrastructure request (the virtual Task P) of 40K in Appendix I of the text. This request is computing infrastructure that is common to the ~100+ HEP personnel resident in Madison. If awarded we would make a suitable distribution across the task budgets. Salaries & Stipends: An inflation rate of 2% was used on the out year salary rates. All salary rates are in accordance with the University policy and procedure. The 100% rate for graduate students for FY08 is $38,064. The majority of the students receive a 59% stipend. Tuition Remission: In 2006 the University instituted a new Tuition Remission Policy. It is a flat fee of 8K per academic year for each student. There is no tuition remission charge for summer graduate research assistants

5 Fringe Benefits: The fringe benefit rates used on all tasks are the current University posted rates for FY08 which are: CATEGORY FY 2007 FY 2008 Academic Staff 35.00% 37.50% Classified Staff 50.00% 46.50% Postdoctoral Associates 24.00% 24.50% Graduate Assistants 27.00% 27.50% Undergraduate Student Hourly 2.00% 2.00% Travel: Since most of our research efforts are off campus, our researchers must do a considerable amount of traveling. We make every effort to obtain the lowest airfare and lodging rates. We use the State/University per diem rate of $40.00/day for domestic trips and apply to foreign travel trips whenever possible. Individual tasks outlined as much of their foreign travel as possible in the task budget narrative. Other Direct Costs: All of the categories under this heading are considered reasonable cost estimates based on our prior year history. Supplies & Services include: postage, telephone, telefax, photocopying, office & laboratory supplies and other related operating expenses. A special note should be made about computing maintenance and supplies: over the years many thousands of dollars have been spent on state of the art computing resources. The maintenance costs for our infrastructure and peripherals is extremely important and shown in each task s individual budget along with computer supplies. Overhead: The overhead is Modified Total Direct Costs (MTDC) with the Off-Campus rate of 26% per DHHS dated 08/09/06. We negotiated with the UW that the off-campus rate is applied to all HEP tasks on the grounds that a significant fraction of our projects are off campus. Tuition remission and equipment are excluded from overhead charges
