Feynman diagram illustrating an alternative production mechanism for glueballs; the glueball (a bound-gluon state predicted by QCD) is accompanied by a charmonium state H. The calculated cross section for this process in e+e- annihilation suggests that recent anomalous results from the Belle Collaboration may be due in part to production of charmonium-glueball pairs.

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!

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 (Host: Hal Metcalf)

PHYSICS AND MATH BUILDING MASONRY REPAIR STATUS:

Masonry probes were performed in 2003 to determine the condition of the masonry facade, corner soldier brick courses, masonry 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, the most awful leaks seem to be gone!

The building

Page 32: The State of the Department Paul Grannis, Sept. 14, 2004 grannis/dept.html

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.

Research highlights of the past year

Physical Sciences and Math research expenditures

~ $13.3M in AY’03 (14th in the nation); highest in the university

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

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

...)

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.

Run-3 submitted to PRL

Run 5 will refine the measurement and help unravel the proton “spin crisis”

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 by recombination of thermal quarks.

Study production asymmetry (ALL) from two polarized protons. This asymmetry is sensitive to the fraction of the proton spin carried by gluons. First publication (A. Deshpande et al.) established the technique and the polarization measurement. The result is consistent with DIS measurement of gluon contribution to proton spin.

COLLIMATING ATOMS WITH COLLIMATING ATOMS WITH THE BICHROMATIC FORCETHE BICHROMATIC FORCE

Why the bichromatic force ???

It’s HUGE, and it spans a

HUGE velocity range!!!

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).

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).

FOCUSING ATOMS WITH FOCUSING ATOMS WITH A DC ELECTRIC FIELDA DC ELECTRIC FIELD

Why electrostatic forces ???

This is a new domain for atom optics and control.

Note – even though these look similar, they are indeed very different images.

Many of our students find good thesis research beyond the Department

Accelerator physics: our adjunct professors Peggs, Ben-Zvi, Litvinenko, MacKay at BNL offer many theoretical and experimental topics. (Note the Accel. Phys course this fall by Waldo MacKay)

Research outside the Department

also opportunities in chemical physics, medical imaging etc.

About 20 students supervised in these external areas.

Particle theory and Lattice Gauge: BNL adjuncts Creutz and Dawson

Condensed Matter and Materials Science at BNL: (Abbamonte, Chaudhari, Davenport, Dierker, P. Johnson, Kao, Ku, Liang, Mazlov, Tsvelik) – both theory and experiment.

Biological Physics: Opportunities in genomics, brain design, bio computation at Cold Spring Harbor Lab (Chklovskii, Zhang); on campus topics in biophysics, structural biology, protein folding, radiation oncology, pharmacology (Kisker, Liang, McLaughlin, S. Smith, J. Wang)

Atmospheric physics: the physics of our atmosphere through the Marine Sciences Research Center (Geller, de Zafra)

Reception outside the Department Office (in the keg circle) follows !

A wealth of exciting physics and astronomy has emerged your work over the past year. I have only scratched the surface (more reports to come in colloquia, seminars, Friday presentations)

The students, research associates and faculty at Stony Brook are recognized as being at the leading edge in many of the most important areas of science.

We welcome the new students to our community, and wish you every success in the exciting enterprises to come.
