Introductory course enrollments continue high. Junior level courses down
somewhat but still larger than we’ve seen in the past.
We continue to need to improve in finding opportunities for research projects
for undergraduates, and the increased number of majors amplifies this need.

2004 Teacher of the year
Emilio Mendez
The great softball challenge
In a warm up for the Olympic games on August 19, the graduate
student Team Tiger took on the dream team, Godzilla made up of
faculty, staff (and a few ringers).
Final score: Team Godzilla 21 (base 4) : Team Tiger 20 (base 8)
Age and treachery will always overcome youth and enthusiasm!
Better luck next year to the grad students!

Simons Lecturers
The bequest by the Simons Foundation will be used this year to sponsor
two special lecturers who will visit the department for a week or more
and give a combination of colloquium and seminar level talks. The
lecturers will also be available for discussions and interactions with
students and faculty.

Lecturers were chosen to present recent theoretical advances of physics
and astronomy, and to represent theoretical fields not strongly
represented at Stony Brook.
Paul Steinhardt of Princeton University will talk on alternatives to big
bang cosmology and quasi-crystals during his visit from Oct. 25 – 29.
(Host: Bill Weisberger)
Sir Michael Berry of the University of Bristol will discuss optical
singularities, chaos and Riemann zeroes, non-hermitian degeneracies and
asymptotic oscillatory phenomena. He will visit Jan. 31 – Feb. 11

PHYSICS AND MATH BUILDING MASONRY REPAIR STATUS:
Masonry probes were performed in 2003 to determine the condition of the
masonry
y facade, corner soldier brick courses, masonry
y column enclosures,
and relieving angle structures by all the windows.
Scope of Work for the masonry repairs are defined. Budgetary Cost
estimates for masonry repair and new roof were completed: $1.86M
We are at the top of the list -- Hoping for the NY State budget to pass!
Over the past year, many repairs made to the AC systems on the roof – new
catchment trays for condensate water, redo plumbing. So far, leaks seem to
be gone!

Research highlights of the past year
This year I asked for one slide that represents the work of each of
the research groupings. Thus this summary is NOT complete, but I
hope that it gives the students a flavor for the research
opportunities that the Department offers.
Organizing principle for areas is from smallest to largest.

Twistor superstrings
(Nair; Witten; Roiban, Spradlin, & Volovich; Berkovits; Vafa; ...)

Old idea (1988), recently revived and extended (December, 2003)
New string theories, for just 4 dimensions
Actually describe particles, not strings
Tailored to describe Quantum Chromodynamics (as part of maximally
supersymmetric Yang-Mills)
Directly give known simple results for tree graphs (Born approximation scattering)
Much simpler than Feynman diagrams; possible replacement
Use topology, twistors, superspace, worldsheet instantons
May generalize to new kinds of QCD strings
Work by Stony Brook people: Roiban (former student); Berkovits (former postdoc);
Siegel (faculty); Giombi, Ricci, Robles-Llana, Trancanelli (students)
One of the topics at the Simons Workshop here, “Superstrings & Topological
Strings”, July 26 - August 27, 2004
Stringy ideas are now influencing understanding of phenomena
observed in the lab; may lead to ability to calculate complex
higher order supersymmetry processes at LHC.

Experiments at RHIC
In central collisions the particle production
associated with both mesons and baryons in
Au Au is similar and significantly higher than
observed in pp and dAu collisions. This
suggests that baryons are produced in jets,
rather than byy recombination of thermal quarks.

Electrostatic forces act on neutral atoms
ONLY through an induced dipole moment, a
process efficient ONLY in Rydberg atoms.
Here the Rydberg states (high n) have been
produced by a novel process and focused to
a small spot. (Thesis of Oleg Kritsun).
Note – even though these look similar, they are indeed very different images.
The bichromatic force offers a new domain of
optical forces to exploit for control of atomic
motion. Here it collimates a metastable He
beam to high intensity and brightness for use in
atomic lithography. (Thesis of Matt Partlow).

RHIC accelerates heavy ions & polarized protons to 100 GeV/A
and is designed to accelerate polarized protons to 250 GeV

Probing the hot, dense matter at RHIC
• Au-Au, d-Au & p-p: Sqrt(s) = 200 GeV
• Mesons & Baryons: pT range:
2 < pT < 4 (GeV/c)
Probability of finding partner hadrons within
the angular region of jet fragmentation is
identical for leading mesons & baryons in
non-central collisions.
In central collisions the hadron production
is significantly higher than observed in pp
and dAu collisions
Peripheral
Baryons from jets are enhanced:

Comment
Run-3 submitted to PRL
– First results on double spin asymmetry in
neutral pion production in pp collisions
which probes ΔG
• Established false asymmetries < 2 x 10-4
• Beam polarimetry: p-p CNI and p-p
elastic developed 2003/2004 (δP/P < 10%)
ΔG Small? Another Spin Crisis? Run 5 will tell us!
