Overview of Talk

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

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 RD
• See Vitaly Yakimenkos talk
• Theory
• Mainly LHC phenomenology lattice QCD
• Detector RD Developing new technology
• ILC detector RD
• 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

  electrostatic quadrupoles and transient magnetic
  field measurements and for analysis of the muon
  g-2 experiment

7
ATLAS - Overview

ATLAS _at_ BNL

• Future Plans
• Analysis Support Center will continue to expand
  as budget permits
• Emphasis on Tier 1 and core software
• RD 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 RD

• New ILC RD detector effort
• Within Collider Physics group
• Part of US ILC detector effort
• Work on far forward (? lt 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

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?

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???) lt 2.7 x 10-7
• Phys. Rev. D 72, 091102 (2005)
• hep-ex/0505069 BR(K? ???) lt 8.3 x 10-9

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

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

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 RD
• 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 labs 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
