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
3
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
4
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
5
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
6
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
7
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

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
10
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
11
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
12
Results from MINOS
m2  0.0031  0.0006 (stat )  0.0001 ( sys ) eV 2
BNL physicists lead NuMI beamline
commissioning, monitoring, and data logging
13
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
14
Reactor Experiment


Precision measurement of sin2213
BNL has joined Daya Bay Experiment
3 yrs running
15
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
16
@ Daya Bay
17
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?

•
LHC, ILC, Neutrino physics
Higher order QCD corrections
Higgs physics
Supersymmetry
3 post-docs

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
22
Kaons
E949, K++
– Last ran in 2002
– Possibility to send some detector components to JPARC: 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)
23
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
24
Small number of Post-docs
All groups need more post-docs to reach their full
potentials

Includes Operating and Capital Expenditures
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
29
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 postdocs to maximize impact
