  1. DOE PROGRAM REVIEW BNL Physics Department S. Dawson April 18, 2006

  2. Overview of Talk • Physics synopsis • Colliders (ATLAS/D0/ILC) • Neutrinos (MINOS/Reactor) • Theory • Future aspirations • Staffing trends/Budgets • Conclusions

  3. Big Picture in the Physics Department • ATLAS is transitioning from construction to the Research Program • Development of Analysis Support Center at BNL • Focus is on PHYSICS • Computing and software to get there! • RSVP cancelled in August, 2005 • Major planning exercise and redirection of program

  4. Planning Exercise • Internal discussions of varied options • Open process with large participation • Clear that a healthy experimental program is broader than ATLAS alone • Also clear that our program needs to be focused on areas where BNL can make unique contributions • BNL program must reflect national priorities • Seminars • ILC, Braidwood, Daya Bay… • Many options considered

  5. Physics Department Priorities • Experiments: Collider Physics and Neutrinos • ATLAS is our top priority (small D0/ILC efforts) • Neutrino effort building up (MINOS/Reactor) • Accelerator R&D • See Vitaly Yakimenko’s talk • Theory • Mainly LHC phenomenology & lattice QCD • Detector R&D: Developing new technology • ILC detector R&D • ATLAS upgrades

  6. Kudos • Sam Aronson, Fellow of AAAS • For leadership in the science and management of experimental particle physics, especially heavy ion physics at Brookhaven National Laboratory • Yannis Semertzides, Fellow of APS • For leadership in the development of electrostatic quadrupoles and transient magnetic field measurements and for analysis of the muon g-2 experiment

  7. ATLAS - Overview • Construction is completing and BNL’s leading role in this has been a big success • Cathode Strip Chambers shipped to CERN • Technical Coordination • U.S. is playing a vital role under David Lissauer’s leadership • M&O: Pre-operation testing of detector components

  8. ATLAS - Overview • Progress in computing software and hardware • Tier 1 Computing Center is building up • BNL computer professionals making important contributions to the ATLAS software • Initiation of PanDa (Production and Distributed Analysis) • Physics Analysis • BNL’s Analysis Support Center is up and running • Many tutorials, meetings and visitors in the last year • Helps US ATLAS community to use ATLAS software

  9. Physics at ATLAS Kranmer

  10. ATLAS @ BNL • Future Plans • Analysis Support Center will continue to expand as budget permits • Emphasis on Tier 1 and core software • R&D on ATLAS upgrade • Work with Instrumentation Division on tracking devices which can withstand a factor of 10 greater luminosity If we get an increase in funding, we will use it for new hires for ATLAS analysis

  11. D0 • D0 effort small at 2.8 physicists • Effort will gradually transition to ATLAS • Transition date planned for end of 2008 • BNL responsibilities in D0 • Forward pre-shower hardware and software • Leadership of  ID group

  12. ILC R&D • New ILC R&D detector effort • Within Collider Physics group • Part of US ILC detector effort • Work on far forward ( < 140 mrad) calorimetry • Luminosity normalization from forward Bhabba pairs • Instantaneous luminosity from beamsstrahlung gammas • BNL role in Experiment Conceptual Design • Have joined SiD detector concept study • Simulation and integration studies • Physics Dept effort coordinated with BNL Instrumentation Division and SMD effort

  13. Results from MINOS BNL physicists lead NuMI beamline commissioning, monitoring, and data logging

  14. Neutrino Effort • MINOS • Ramps down in 2010 (?) • 4.9 physicist FTEs • Increased by 1 after RSVP cancellation • LDRD supported 1.8 FTEs in FY05, who are now on core funding • Group is at optimal size • Additional physicist effort allows increased analysis role • Search for e appearance in far detector

  15. Reactor Experiment • Precision measurement of sin2213 • BNL has joined Daya Bay Experiment 3 yrs running

  16. Reactor Experiment to Measure 13 Visit to Daya Bay (Feb 11-18) • Focus on formal collaboration issues • US. Co-spokesman, K. Luk • Executive Board, US representatives, Luk/McKeown • Institutional Board, BNL representative, Kettell • Developing BNL role • BNL has large representation on task forces which will finalize design • BNL might provide Muon Tracker, simulations, project management • BNL Chemistry department will provide Gd loaded liquid scintillator

  17. @ Daya Bay

  18. Very Long Baseline Neutrino Experiment • Neutrinos from FNAL to DUSEL • Large detector and beam will be proposed separately from DUSEL • Could use upgraded beam from Fermilab with ~1 MW • Construction of large detector 2010-2017? • National Effort • Workshop with FNAL March 6-7, 2006 • Start of BNL/FNAL physics study of very long baseline experiments • What are physics trade-offs of various detector/beam options?

  19. Possible timeline for Neutrino Efforts MINOS: Data taking and analysis Reactor: Construction Data taking R&D Construction Data taking VLBNO: 2005 2010 2015

  20. Physics Department Experimental Efforts LSST 1 FTE ILC Detectors (SiD Collaboration) 13.1 FTE D0 ATLAS MINOS 4.9 FTE Reactor (Daya Bay) VLBLNO 2005 2010 2015

  21. Theory • Group is oriented towards phenomenology • LHC, ILC, Neutrino physics • Higher order QCD corrections • Higgs physics • Supersymmetry • 3 post-docs Krupovnickas

  22. Theory • Lattice gauge theory for weak interaction matrix elements • Direct benefit from interactions in department • RBRC Center (~ 5 Lattice post-docs, many visitors, QCDOC computer) • Karsch Lattice Gauge Theory Group (~6 physicists) focussed on finite temperature QCD

  23. Kaons • E949, K++ • Last ran in 2002 • Possibility to send some detector components to J-PARC: depends on Japanese funding • Final data analysis complete in coming year • Recent physics results: • hep-ex/0506028: BR(0) < 2.7 x 10-7 • Phys. Rev. D 72, 091102 (2005) • hep-ex/0505069: BR(K+ +) < 8.3 x 10-9 • Physics LettersB623, 192 (2005)

  24. Other Issues • g-2 awaits P5 decision in September, 05 • If g-2 goes forward, BNL physicists will play important roles • Small LSST effort formed • 1 core FTE + 1 FTE funded by lab • Work on camera sensors for LSST with Instrumentation • Requires strategic hire of experimental astrophysicist and build up of engineering effort for success

  25. Small number of Post-docs • All groups need more post-docs to reach their full potentials Year

  26. Shrinking Technical Staff Technicians in Physics Department Engineers in Physics Department

  27. Staffing Trends • Total staff • FY05: 92 FTE • FY06: 89 FTE • Growth in LHC Research Program computing professionals • FY05: 15 FTE • FY06: 21.3 FTE • Number of physicists on LHC/D0 unchanged • FY05: 9.7 (LHC), 2.7 (D0) • FY06: 10.3 (LHC), 2.8 (D0) • Growth in Neutrino physicists • FY05 1.8 FTE • FY06 4.9 FTE • Total Physicists decreased • FY05 41.1 FTE • FY06 36.3 FTE 10% decrease!!!

  28. More Staffing Trends in Physics Dept • RSVP group • FY05: 10 physicists, 1.2 engineers, 2.3 techs • FY06: • 3 to Neutrinos • 3 to ATLAS • 1 to LSST • 1 to ILC R&D • 1 to accelerator division • 1 to NSF • Engineer to NSLS-II • Core research staff (all categories; non-LHC project ) • FY05: 57.4 FTE • FY06: 48.8 FTE Where RSVP physicists went Large reduction in staff

  29. Budgets Non-LHC funding * Bottom Line: FY07 budget will allow us to maintain staff, but not expand ATLAS physics effort *Reactor Experiment put in Non-Accelerator Physics Budget Code in lab’s request for FY07

  30. Conclusion • Reorganization of experimental program into two major efforts following RSVP cancellation • Collider physics: ATLAS/D0/ILC • Neutrinos: MINOS/Reactor/VLBO • We are moving aggressively to implement plans • FY07 budget allows continuation of effort at current level, but not(highly desired!)expansion of ATLAS physics effort • ALL efforts need increased number of post-docs to maximize impact
