Topics in Nuclear Physics
- The Phase-Diagram of Nuclear Matter:
- The QCD phase diagram exhibits a large number of different phases
including normal nuclear matter, dense hadron matter, quark gluon plasma,
color super conductors. Discuss the phase diagram and its characteristic
features and their theoretical basis. Explain which parts can be addressed
by which experimental techniques.
(Drees, Shuryak, Hemmick, Teaney,Kharzeev)
- The Perfect Fluid Created at RHIC:
- The hot, dense matter formed at RHIC has shown surprising
properties. It is extremely opaque to colored probes (quarks and gluons)
traversing it. The matter thermalizes incredibly quickly and behaves
like a liquid with extremely small viscosity. Screening of the color
charges does not appear to be complete. Similar properties are observed
in strongly coupled plasmas, and are being studied using the
correspondence of string theory and quantum field theory. Discuss either
the experimental evidence for strongly coupled plasma formation or
theoretical studies of its properties utilizing AdS/CFT correspondence.
(Zahed, Teaney,Kharzeev Shuryak, Jacak)
- Quenching of Jets and Heavy Quark Energy Loss:
Jets of particles in the final state of a collision arise from quarks or
gluons scattering with large momentum transfer. In heavy ion collisions
the quarks or gluons lose a large amount of energy in the dense medium
as they traverse it. Even the very heavy charm quarks experience huge
energy losses, which is quite surprising. Furthermore, the deposited
energy appears to create a sound wave in the medium. Discuss the
results, focusing on either theoretical or experimental aspects.
(Drees, Jacak, Shuryak, Teaney,Kharzeev)
- J/Psi suppression, a signature for deconfinement of
- In collisions of heavy ions fewer J/psi mesons are produced than expected
from summing independent nucleon-nucleon collisions. This was predicted as a
signature of quark-gluon plasma formation. Briefly describe the concept of
quark gluon plasma. Discuss the mechanism of suppression of the J/psi and
recent data. (Drees, Hemmick)
- Electromagnetic Radiation from Hot, Dense Nuclear Matter:
Enhanced radiation of lepton pairs from the hot and dense reaction
volume created in collision of nuclei was observed at CERN and now also
at RHIC. The data indicate melting of the QCD vacuum and therefore the
presence of a QCD phase transition. Show the experimental results and
(Drees, Hemmick, Zahed)
- Statistical Mechanics of Nuclear Collisions:
- The number and spectra of particles produced in heavy ion collisions is
well described by statistical emission from an equilibrated gas of hadrons.
Data indicate that hadrons decouple at a temperature near 170 MeV, near the QCD
phase transition between quarks and hadrons. Describe the measurements,
statistical analysis and interpretation. (Shuryak, Jacak,
- Particle Interferometry:
- The space-time extent of the collision region formed in nuclear reactions
can be studied by measuring the interference between two identical outgoing
particles. Measurements at RHIC show a surprise: the sizes are no larger than
at lower energy, even though RHIC produces more particles and more explosive
collisions. Explain the technique and discuss the recent results. (Teaney,Kharzeev, Jacak,
- Collective Flow of Quark Gluon Plasma
Heavy ion collisions produce high pressure and hydrodynamic flow,
resulting in non-isotropic particle emission patterns. The anisotropy at
RHIC is large and indicates rapid equilibration and very low viscosity
followed by hydrodynamic expansion. Discuss the phenomenon and how
plasma parameters are extracted from it.
(Teaney,Kharzeev, Shuryak, Hemmick)
- Strongly coupled quark-gluon plasma(s)
- The AdS/CFT correspondence and applications to strongly coupled plasmas.
- Color Superconductivity and QCD at High Density
Quark matter at high density is believed to display a number of
interesting phases, with quark Cooper pairs condensing like in an
ordinary superconductor. Those pairs are diquarks which are already
observed inside the ordinary nucleons.
- Where are the quarks inside nuclei?
- Discuss scattering of leptons from nuclei and dilepton production via the
Drell-Yan process to probe quark and antiquark distributions. What do we learn
from such data about the quark structure functions, and what is the effect of
the nuclear medium? (Deshpande, Jacak, Marx)
- Where is the spin of the proton?
Results from deep inelastic scattering experiments using longitudinally
polarized electrons and polarized protons indicate that the quark spin
contribution to the spin of the proton is essentially zero. This result
is commonly referred to as the “Spin Crisis”. The gluons contribution
to the proton spin is studied with polarized protons at RHIC. Review the
DIS and polarized proton experiments and results.
(Deshpande, Shuryak, Qiu)
- What is the role of anti-quarks in determining the proton spin?
Polarized deep inelastic scattering experiments can not distinguish
and anti-quark spin contributions, since the interactions carriers
(virtual photons, in DIS) do not carry color charge. A recent Fermilab
experiment suggests that the anti-down and anti-up quarks have
substantially different linear momentum distributions at high energies,
indicating that the spins carried by quarks and anti-quarks probably do
not cancel. Review these results and discuss how RHIC spin program at
BNL plans to measure the anti-quark (ubar and dbar) spin contributions
(Deshpande, Shuryak, Qiu)
- What is the transverse spin structure of the proton?
Results from *transversely* polarized proton-proton and electron-proton
scattering experiments have measured large left-right asymmetries in
production in the final state. A comprehensive understanding of these
observations is key to the three dimensional structure of the proton,
quark and gluon orbital angular momentum contribution to the proton
spin. Review these experimental observations and discuss attempts to
understand the transverse spin structure of the proton at Brookhaven
or/and at Jefferson Laboratory.
(Deshpande, Jacak, Shuryak, Qiu)
- Measurements of the Electron Neutrino Mass:
- Discuss the various experiments to measure electron neutrino masses from
beta-decay endpoint measurements and double-beta decay. Give the latest results
and discuss the relation of these results to the recent observations of
neutrino oscillations. (Shrock, Jung)
- Super-Heavy Nuclei:
Well-founded nuclear model calculations have predicted a stable
(lifetimes between 1 and 100 years) island of very heavy nuclei near
Z--114 and A--300. A few such nuclei have recently been detected.
Discuss the theoretical basis for the super-heavy island and the
possible approaches to it by use of heavy ion reactions. Discuss the
results from recent experiments.
- Nuclear Liquid-Gas Phase Transition:
Under the influence of heat and pressure nuclear matter is expected to
undergo a liquid-gas phase transition. This is the boiling point of
nuclear matter. Report on recent experiment showing fragmentation of
nuclei into large clusters (droplets) at intermediate energies (several
100 MeV/u) which are interpreted in terms of such a phase transition.
Discuss the theoretical connection of these experiments with a phase
transition from a nuclear liquid to a nuclear gas phase.
- Carbon 14 Dating:
Radiometric dating with carbon 14 is a widely accepted process for determining the age
of plant and animal remains. The utility of carbon 14 for radiometric dating follows
from the slow decay rate of carbon 14, which has only recently been understood.
- Topology, Spin and Symmetry in nucleons and nuclear collisions:

Unification of the elementary forces in the neighborhood of the electroweak
scale (1 TeV) by postulating the existence of "large" (µm to mm)
extra dimensions. Review existing and ongoing experimental research in gravity
at the sub-millimeter scale, and predictions for physics at the Tevatron and
the large hadron collider LHC at CERN. (Van Nieuwenhuizen, Hobbs,
- Parton Structure of the Proton:
- How do we measure the quark and gluon distributions in the proton? How do
they vary with q-squared? What is the spin content of the proton?
- Precision Measurement of the W Boson Mass:
- Discuss the precision measurement of the W mass at the FNAL TeVatron
collider by the DØ and CDF collaborations and by the four LEP
collaborations. Discuss the measurement methods and the achieved precision.

test of one's understanding of the detector. (Rijssenbeek, McCarthy)
- Detection of Neutrinos from the Sun:
- Discuss the major ongoing experiments (Super-Kamiokande, SNO, Davis,

experiments. (Jung, McGrew, Yanagisawa,Gonzalez-Garcia)
- Long Baseline Neutrino Oscillation Experiments and Lepton Mixing Matrix:
- Observations of neutrino oscillations by the underground experiments in the
atmospheric and solar neutrinos have revolutionized the particle physics. There
are efforts to further confirm this findings using accelerator produced
neutrino beams and to measure the lepton mixing matrix elements, which doesn't
exist in the Standard Model. Give the latest results from the K2K experiment
and summarize the plans for new experiments (MINOS, CNGS and JHFnu). (Jung,
McGrew, Yanagisawa, Shrock, Gonzalez-Garcia)
- The Nature and Magnitude of the Neutrino Mass:
- The neutrino oscillation signal observed by several experiments implies
that neutrinos have a small, but finite mass. Discuss the implication of
neutrino mass for the standard model of particle physics and what is known
about the mass from neutrino oscillation experiments, direct mass searches,and
neutrinoless double beta-decay experiments. Describe the experimental
techniques use in either a direct mass, or a double beta-decay
