Virtual Compton Scattering at High Energy

Zhang Chen

In this dissertation we develop a theoretical framework in the context of perturbative QuantumChromoDynamics (pQCD) for studying non-forward scattering processes. In particular, we…

Hydrodynamics of nuclear matter in the chiral limit

D. T. Son

Using the Poisson bracket method, we construct the hydrodynamics of nuclear matter in the chiral limit, which describes the dynamics of all low-energy degrees of freedom, including…

Hadron yields from thermalized minijets at RHIC and LHC

N. Hammon, H. Stöcker, W. Greiner +1

We calculate the yields of pions, kaons, and -mesons for RHIC and LHC energies assuming thermodynamical equilibration of the produced minijets, and using as input results from p…

Small-x Physics, High Parton Densities and Parton Saturation in QCD

A. H. Mueller

Partons are defined as the quanta in a Fock space description of a hadron. Gluon saturation is described in the Weizsäcker-Williams approximation for a large nucleus. The elements…

Dynamical lattice QCD thermodynamics with domain wall fermions

George T. Fleming

We present results from simulations of two flavor QCD thermodynamics at N_t=4 with domain wall fermions. In contrast to other lattice fermion formulations, domain wall fermions pre…

The Standard Model in Its Other Phase

Stuart Samuel

The standard model of particle physics is analyzed for the case of a Higgs potential not favoring spontaneous electroweak symmetry breaking to gain insight into the physics of the…

Inverse meson mass ordering in color-flavor-locking phase of high density QCD

D. T. Son, M. A. Stephanov

We derive the effective Lagrangian for the low-energy massive meson excitations of the color-flavor-locking (CFL) phase of QCD with 3 flavors of light quarks. We compute the decay…

Phi, Omega and Rho production from deconfined matter in relativistic heavy ion collisions at CERN SPS

Peter Csizmadia, Peter Levai

We investigate the production of the Phi meson and the Omega baryon which interact weakly with hot hadronic matter, and thus their spectra reflect the early stage of the heavy ion…

The Boltzmann equation for gluons at early times after a heavy ion collision

A. H. Mueller

A Boltzmann equation is given for the early stages of evolution of the gluon system produced in a head-on collision. The collision term is taken from gluon- gluon approximation. <…

Jet Quenching in Thin Quark-Gluon Plasmas I: Formalism

Miklos Gyulassy, Peter Levai, Ivan Vitev

The modification and amplification of the gluon angular distribution produced along with hard jets in nuclear collisions is computed. We consider the limit of a thin quark-gluon pl…

Jet quenching in thin plasmas

Miklos Gyulassy, Peter Levai, Ivan Vitev

We investigate the energy loss of quarks and gluons produced in hard processes resulting from final state rescatterings in a finite quark-gluon plasma. The angular distribution of…

Angular Dependence of the Radiative Gluon Spectrum and the Energy Loss of Hard Jets in QCD Media

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

The induced momentum spectrum of soft gluons radiated from a high energy quark propagating through a QCD medium is derived in the BDMPS formalism. A calorimetric measurement for th…

Toward Equilibration in the Early Stages After a High Energy Heavy Ion Collision

A. H. Mueller

The early stages in the evolution of the gluons produced in the central region of a head-on high-energy heavy ion collision is studied. An equation is given for the rate of change…

Transverse Momentum Dependence of the Landau-Pomeranchuk-Migdal Effect

Urs Achim Wiedemann, Miklos Gyulassy

We study the transverse momentum dependence of the Landau-Pomeranchuk-Migdal effect in QED, starting from the high energy expansion of the solution of the Dirac equation in the pre…

Parton Saturation at Small x and in Large Nuclei

A. H. Mueller

Quark and gluon distributions in the light-cone wavefunction of a high energy hadron or nucleus are calculated in the saturation regime. One loop calculations are performed explici…

Universal pion freeze-out phase-space density

D. Ferenc, U. Heinz, B. Tomasik +2

Results on the pion phase-space density at freeze-out in sulphur-nucleus, Pb-Pb and pi-p collisions at the CERN SPS are presented. All heavy-ion reactions are consistent with the t…

QCD and Nuclear Physics

A. H. Mueller

The main part of this talk is a review and summary of how QCD is used in two main areas of nuclear physics, namely in determining the quark flavor and spin content of the proton an…

Correlations for Mass-Shifted Bosons

T. Csorgo, M. Gyulassy

We discuss a new kind of correlation, the correlation of particle-antiparticle pairs emitted back-to-back in the local rest frame of a medium, if medium effects cause mass modifica…

Indirect Detection of Neutralino Annihilation from Three-body Channels

Xuelei Chen, Marc Kamionkowski

Three-body final states are included in the calculation of cross section and neutrino production in neutralino annihilations. In some regions of the parameter space, three-body cha…
