QCD-like Theories at Finite Baryon and Isospin Density

K. Splittorff, D. T. Son, M. A. Stephanov

We use 2-color QCD as a model to study the effects of simultaneous presence of chemical potentials for isospin charge, , and for baryon number, . We determine the phase d…

Domain walls of high-density QCD

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

We show that in very dense quark matter there must exist metastable domain walls where the axial U(1) phase of the color-superconducting condensate changes by 2pi. The decay rate o…

QCD at finite isospin density: from pion to quark-antiquark condensation

D. T. Son, M. A. Stephanov

QCD at finite isospin chemical potential mu_I is studied. This theory has no fermion sign problem and can be simulated on the lattice using present-day techniques. We solve this th…

Hydrodynamics of relativisic systems with broken continuous symmetries

D. T. Son

We show how hydrodynamics of relativistic system with broken continuous symmetry can be constructed using the Poisson bracket technique. We illustrate the method on the example of…

Asymptotic deconfinement in high-density QCD

D. H. Rischke, D. T. Son, M. A. Stephanov

We discuss QCD with two light flavors at large baryon chemical potential mu. Color superconductivity leads to partial breaking of the color SU(3) group. We show that the infrared p…

Fermions, Gauge Theories, and the Sinc Function Representation for Feynman Diagrams

Dmitri Petrov, Richard Easther, Gerald Guralnik +2

We extend our new approach for numeric evaluation of Feynman diagrams to integrals that include fermionic and vector propagators. In this initial discussion we begin by deriving th…

Event-by-Event Fluctuations from Decay of a Polyakov Loop Condensate

Adrian Dumitru, Robert D. Pisarski

A model for particle production at the deconfining phase transition in QCD is developed, as the semi-classical decay of a condensate for the Polyakov loop. In such a model, generic…

Bottom-up thermalization in heavy ion collisions

R. Baier, A. H. Mueller, D. Schiff +1

We describe how thermalization occurs in heavy ion collisions in the framework of perturbative QCD. When the saturation scale is large compared to , thermalization t…

First-Order Chiral Phase Transition in High-Energy Collisions: Can Nucleation Prevent Spinodal Decomposition?

O. Scavenius, A. Dumitru, E. S. Fraga +2

We discuss homogeneous nucleation in a first-order chiral phase transition within an effective field theory approach to low-energy QCD. Exact decay rates and bubble profiles are ob…

On the Relationship between Large Order Graphs and Instantons for the Double Well Oscillator

A. H. Mueller, D. N. Triantafyllopoulos

The double well oscillator is used as a QCD-like model for studying the relationship between large order graphs and the instanton-antiinstanton solution. We derive an equation for…

Searching for the Lightest Neutralino at Fixed Target Experiments

L. Borissov, J. Conrad, M. Shaevitz

Most ongoing supersymmetry searches have concentrated on the high-energy frontier. High-intensity fixed target beamlines, however, offer an opportunity to search for supersymmetric…

The Effective Pressure of a Saturated Gluon Plasma

Adrian Dumitru, Miklos Gyulassy

The evolution of the gluon plasma produced with saturation initial conditions is calculated via transport theory for nuclear collisions with 0.1 <sqrt(s) <10 A TeV. The effective l…

Report of the Working Group on Photon and Weak Boson Production

U. Baur, E. L. Berger, H. T. Diehl +18

This report discusses physics issues which can be addressed in photon and weak boson production in Run II at the Tevatron. The current understanding and the potential of Run II to…

QCD at finite isospin density

D. T. Son, M. A. Stephanov

QCD at finite isospin chemical potential mu_I has no fermion sign problem and can be studied on the lattice. We solve this theory analytically in two limits: at low mu_I where chir…

Nonlinear evolution of the momentum dependent condensates in strong interaction: the ``pseudoscalar laser''

Adrian Dumitru, Ove Scavenius

We discuss the relaxation of the scalar and pseudoscalar condensates after a rapid quench from an initial state with fluctuations. If we include not only the zero-mode but also hig…

Equilibration of the Gluon-Minijet Plasma at RHIC and LHC

Gouranga C. Nayak, Adrian Dumitru, Larry McLerran +1

We study the production and equilibration of the gluon-minijet plasma expected to be formed in the central region of ultrarelativistic heavy-ion collisions at the BNL-RHIC and the…
