Topics in Nuclear Physics

Jet Quenching: Particle jets arise from quarks or gluons scattered with large momentum transfer. In heavy ion collisions the scattered quarks and gluons traverse matter and should lose a large amount of energy if the density is high. Jet quenching was recently observed in PHENIX. Discuss the result, focusing on either theoretical or experimental aspects.
Jacak, Drees

J/Psi suppression, a signature for deconfinement of quarks: 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, Jacak

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, Prakash, Jacak, Hemmick

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.
Jacak, Hemmick, Brown, Shuryak

Elliptic Flow of Matter The high particle multiplicity in heavy ion collisions produces high pressure and non-isotropic particle emission patterns. The anisotropy at RHIC is large and indicates rapid equilibration followed by hydrodynamic expansion. Discuss the phenomenon and to what extent it indicates quark gluon plasma formation.
Shuryak, Hemmick

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?
Jacak, Marx

Where is the spin of the proton? Results from deep inelastic scattering experiments using polarized electrons and polarized protons indicate that the quark spin contribution to the spin of the proton is essentially zero. Review these experiments and discuss upcoming attempts at Brookhaven to measure the polarization of gluons inside the proton.
Jacak, Schaefer, Shuryak

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

Parity Non-conservation in Atoms: The strength of parity violating transitions in atoms allow determination of standard-model parameters at low q-squared. Discuss the experiments and the model sensitivities.
Sprouse, Orozco

Nuclear Sizes and Moments from Hyperfine Laser Spectroscopy: Precise data on nuclear charge radii and electromagnetic moments can be obtained from hyperfine spectroscopy using lasers. Discuss how these experiments are done. Give examples of deduced nuclear properties such as the nuclear compressibility. Also discuss the use of laser spectroscopy to trap radioactive ions to study parity non-conservation in atomic transitions.

Nuclear Structure at the Extremes of Neutron-Proton (Isospin) Imbalance: Topics include - physics at the proton/neutron drip-lines, n-p pairing, neutron halo nuclei, radio active beam (RIB) facilities, octupole deformations in fission fragments. Concentrate on one of these subjects.

Nuclear Structure at Extreme Angular Momentum: Super-deformed (axis ratio 2:1) nuclear states have been identified at angular momenta up to 70. Discuss the theoretical basis why axis ratios of 2:1 and even 3:1 are stable. Explain recent experiments which use the large Ge arrays to measure super and hyper-deformed bands in a systematic fashion.

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--1 14 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 (somewhat controversial) results from recent experiments.
Sprouse, Jacak

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.

Topics in Elementary Particle Physics

Discovery of the Top Quark: Discuss the discovery and the measurements of top quark production cross section and the top quark mass by the DØ and CDF experiments. Discuss the signatures and methods used, and the significance of the precise measurement of the top quark mass for the prediction of the Higgs boson mass.
Grannis, Hobbs

Search for the Higgs Boson: Discuss the search for the Standard Model Higgs boson which will be carried out at LEP, at the upgraded TeVatron, and at the Large Hadron Collider. What are the different strategies as function of the mass and the prospects for success?
Grannis, Hobbs, Rijssenbeek

Precision Measurement of the Z Boson Parameters: Measurements at the SLAC SLC collider and the CERN LEP collider of the Z boson mass, width, and production cross section. Relevance to tests of the Standard Model.
Hobbs, Grannis, Rijssenbeek

Large Extra dimensions and Grand Unification at the Electroweak Scale: Discuss the recent theoretical developments in trying to obtain Grand Unification of the elementary forces in the neighborhood of the electroweak scale (1 TeV) by postulating the existence of "large" (mmm 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, Rijssenbeek

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 two measurement methods and the achieved and predicted precision. Explain its importance as a test of the Standard model.
Rijssenbeek, Grannis

Detection of Neutrinos from the Sun: Discuss the major ongoing experiments (Super-Kamiokande, SNO, Davis, Gallex/GNO, Sage) that measure the flux of solar neutrinos.

Jung, McGrew, Yanagisawa, Gonzalez-Garcia

Detection of Neutrinos from Supernovae: Neutrinos from the supernova SN1987a are the only astrophysical neutrinos observed other than solar neutrinos. Discuss the supernova neutrino production mechanism, observation of neutrinos from SN1987a, experimental observation methods and future prospects.
Jung, Yanagisawa, Lattimer

Atmospheric Neutrinos and Neutrino Oscillations: Discuss the origin of atmospheric neutrinos and the expected fluxes of electron-type and muon-type neutrinos. Discuss the experimental measurements that differ from the predicted values and possible explanations for the discrepancy. And finally discuss the recent Super Kamiokande results that show evidence for neutrino oscillations, and supporting evidences from other experiments.
Jung, McGrew, Yanagisawa

Ultra High Energy Cosmic Ray Events: There are two ground based experiments: AGASA and HiRES that claims to observe cosmic ray events beyond so called "GZK cut-off". These events are the highest known particle interaction events (~10e20 eV). Explain GZK cut-off. Give the latest results from these experiments and explore possible scenarios/explanations for these extraordinary events. Summarize the plans for new experiments.
Jung, McGrew, Yanagisawa

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
