Buckyballs and gluon junction networks on the femtometer scale

T. Csorgo, M. Gyulassy, D. Kharzeev

We explore the possibility that novel geometrical structures analogous to carbon Fullerenes may exist in Nature on the femtometer scale. QCD predicts the existence of special topol…

Supernova Neutrinos and the LSND Evidence for Neutrino Oscillations

Michel Sorel, Janet Conrad

The observation of the energy spectrum from a supernova burst can provide constraints on neutrino oscillations. We derive formulas for adiabatic oscillations of supernova…

Modelling correlations in heavy ion collisions

T. Csorgo, A. Ster

Modelling correlations in heavy ion collisions is reviewed from model independent characterization of the two-particle correlations to Buda-Lund hydro model fits to correlations an…

Strangeness Production as a Diagnostic Tool for Understanding Heavy Ion Reactions

J. L. Nagle

Strangeness production has long been proposed as a diagnostic tool for understanding the dynamics of relativistic heavy ion collisions. In this presentation we review the tradition…

The gluon plasma at RHIC

Denes Molnar

Differential elliptic flow and particle spectra are calculated from covariant Boltzmann transport theory taking into account the finite transport opacity of the gluon plasma produc…

Pion Propagation near the QCD Chiral Phase Transition

D. T. Son, M. A. Stephanov

We point out that, in analogy with spin waves in antiferromagnets, all parameters describing the real-time propagation of soft pions at temperatures below the QCD chiral phase tran…

A Simple Derivation of the JIMWLK Equation

A. H. Mueller

A simple derivation of the Jalilian-Marian, Iancu, McLerran, Weigert, Leonidov and Kovner (JIMWLK) equation for the evolution of small-x QCD wavefunctions is given. The derivation…

Cosmology with a long range repulsive force

Martina Brisudova, William H. Kinney, Richard Woodard

We consider a class of cosmological models in which the universe is filled with a (non-electric) charge density that repels itself by means of a force carried by a vector boson wit…

Kaon Condensation and Goldstone's Theorem

T. Schaefer, D. T. Son, M. A. Stephanov +2

We consider QCD at a nonzero chemical potential for strangeness. At a critical value of the chemical potential equal to the kaon mass, kaon condensation occurs through a continuous…

Neutrinos as the messengers of CPT violation

G. Barenboim, L. Borissov, J. Lykken +1

CPT violation has the potential to explain all three existing neutrino anomalies without enlarging the neutrino sector. CPT violation in the Dirac mass terms of the three neutrino…

Sensitivity to the KARMEN Timing Anomaly at MiniBooNE

S. Case, S. Koutsoliotas, M. L. Novak

We present sensitivities for the MiniBooNE experiment to a rare exotic pion decay producing a massive particle, Q^0. This type of decay represents one possible explanation for the…

The Potential for Neutrino Physics at Muon Colliders and Dedicated High Current Muon Storage Rings

I. Bigi, T. Bolton, J. Formaggio +11

Conceptual design studies are underway for muon colliders and other high-current muon storage rings that have the potential to become the first true ``neutrino factories''. Muon de…

Degrees of Freedom and the Deconfining Phase Transition

Adrian Dumitru, Robert D. Pisarski

There is a sharp increase in the relative number of degrees of freedom at the deconfining phase transition. Characterizing this increase using the Polyakov Loop model, we find that…

On the Angular Dependence of the Radiative Gluon Spectrum

R. Baier, Yu. L. Dokshitzer, A. H. Mueller +1

The induced momentum spectrum of soft gluons radiated from a high energy quark produced in and propagating through a QCD medium is reexamined in the BDMPS formalism. A mistake in o…

How Protons Shatter Colored Glass

Adrian Dumitru, Larry McLerran

We consider the implications of the Color Glass Condensate for the central region of p+A collisions. We compute the k_t distribution of radiated gluons and their rapidity distribut…

Instanton interactions in dense-matter QCD

D. T. Son, M. A. Stephanov, A. R. Zhitnitsky

A Coulomb gas representation of dense-matter QCD is derived from a dual transformation of the low-energy effective Lagrangian. The point-like charges Q=+1,-1 of the gas are identif…

Implications of muon anomalous magnetic moment for supersymmetric dark matter

E. A. Baltz, P. Gondolo

The anomalous magnetic moment of the muon has recently been measured to be in conflict with the Standard Model prediction with an excess of 2.6 sigma. Taking the excess at face val…

Explosive Decomposition in Ultrarelativistic Heavy Ion Collision

O. Scavenius, A. Dumitru, A. D. Jackson

Recent results from Au+Au collisions at BNL-RHIC energy hint at explosive hadron production at the QCD transition rather than soft hydrodynamic evolution. We speculate that this is…

Nuclear Broadening Effects on Hard Prompt Photons at Relativistic Energies

A. Dumitru, L. Frankfurt, L. Gerland +2

We calculate prompt photon production in high-energy nuclear collisions. We focus on the broadening of the intrinsic transverse momenta of the partons in the initial state from nuc…

Impact parameter dependent S-matrix for dipole-proton scattering from diffractive meson electroproduction

S. Munier, A. M. Stasto, A. H. Mueller

We extract the S-matrix element for dipole-proton scattering using the data on diffractive electroproduction of vector mesons at HERA. By considering the full t dependence of this…

Explosive Collisions at RHIC?

Adrian Dumitru, Robert D. Pisarski

Motivated by experimental results from RHIC, we suggest how a condensate for the Polyakov loop might produce explosive behavior at the QCD phase transition. This is due to a rapid…

Testing cosmological supersymmetry breaking

Daniel Kabat, Arvind Rajaraman

Banks has proposed a relation between the scale of supersymmetry breaking and the cosmological constant in de Sitter space. His proposal has a natural extension to a general FRW co…

Vector Meson Production in the Golec-Biernat Wuesthoff Model

Allen C. Caldwell, Mara S. Soares

We apply the Golec-Biernat Wuesthoff model in the calculation of vector meson photo- and electroproduction. Starting from very simple non-relativistic wave functions we show that t…
