On the equivalence between the Boltzmann equation and classical field theory at large occupation numbers

A. H. Mueller, D. T. Son

We consider a system made up of exictations of a neutral scalar field, ϕ, having a λϕ^4 interaction term. Starting from an ensemble where the occupation number f is large, but λf i…

Observational Tests of Open Strings in Braneworld Scenarios

Katherine Freese, Matthew Lewis, Jan Pieter van der Schaar

We consider some consequences of describing the gauge and matter degrees of freedom in our universe by open strings, as suggested by the braneworld scenario. We focus on the geomet…

High-p_T Tomography of d+Au and Au+Au at SPS, RHIC, and LHC

Ivan Vitev, Miklos Gyulassy

The interplay of nuclear effects on the p_T > 2 GeV inclusive hadron spectra in d+Au and Au+Au reactions at root(s) = 17, 200, 5500 GeV is compared to leading order perturbative QC…

The Energy Dependence of the Saturation Momentum from RG Improved BFKL Evolution

D. N. Triantafyllopoulos

We study the energy dependence of the saturation momentum in the context of the collinearly improved Leading and Next to Leading BFKL evolution, and in the presence of saturation b…

Neutrino Propagation in a Weakly Magnetized Medium

Sushan Konar, Subinoy Das

Neutrino-photon processes, forbidden in vacuum, can take place in the presence of a thermal medium and/or an external electro-magnetic field, mediated by the corresponding charged…

QCD in Nuclear Collisions

Alfred H. Mueller

The relationship between RHIC and HERA data is explored using the idea of saturation (color glass condensate) as a unifying framework for interpretation. A description of the early…

High-p_T Pion Quenching versus anti+Baryon Enhancement in Nucleus-Nucleus Collisions

Ivan Vitev, Miklos Gyulassy

Jet quenching of quarks and gluons in central A+A collisions suppresses the high-p_T meson production and exposes novel baryon dynamics that we attribute to (gluonic) baryon juncti…

Gluon Distributions and Color Charge Correlations in a Saturated Light-cone Wavefunction

Alfred Mueller

We describe the light-cone wavefunction in the saturation regime in terms of the density of gluons per unit of transverse phase space, the occupation number, and in terms of the co…

QCD vacuum structure in strong magnetic fields

Daniel Kabat, Kimyeong Lee, Erick Weinberg

We study the response of the QCD vacuum to strong magnetic fields, using a potential model for the quark-antiquark interaction. We find that production of spin-polarized u-ubar pai…

The Energy Dependence of the Saturation Momentum

A. H. Mueller, D. N. Triantafyllopoulos

We study BFKL evolution and, in particular, the energy dependence of the saturation momentum in the presence of saturation boundaries limiting the region of linear BFKL evolution.…

Cosmology with a long-range repulsive force

William H. Kinney, Martina Brisudova, Richard Woodard

We discuss the properties of a cosmology dominated by a charged scalar field with a repulsive, long-range self-interaction. The interaction, in the form of a vector field with a ti…

Potential for Supernova Neutrino Detection in MiniBooNE

Matthew K. Sharp, John F. Beacom, Joseph A. Formaggio

The MiniBooNE detector at Fermilab is designed to search for oscillation appearance at and to make a decisive test of the LSND signal. The main d…

Does parton saturation at high density explain hadron multiplicities at RHIC ?

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

We discuss the recent claim that hadron multiplicities measured at RHIC energies are directly described in terms of gluon degrees of freedom fixed from the initial conditions of ce…

CPT Violation and the Nature of Neutrinos

G. Barenboim, J. F. Beacom, L. Borissov +1

In order to accommodate the neutrino oscillation signals from the solar, atmospheric, and LSND data, a sterile fourth neutrino is generally invoked, though the fits to the data are…

Magnetic permeability of near-critical 3d abelian Higgs model and duality

D. T. Son

The three-dimensional abelian Higgs model has been argued to be dual to a scalar field theory with a global U(1) symmetry. We show that this duality, together with the scaling and…

Physics at Future Hadron Colliders

U. Baur, R. Brock, J. Parsons +7

We discuss the physics opportunities and detector challenges at future hadron colliders. As guidelines for energies and luminosities we use the proposed luminosity and/or energy up…

Neutrinos that violate CPT, and the experiments that love them

G. Barenboim, L. Borissov, J. Lykken

Recently we proposed a framework for explaining the observed evidence for neutrino oscillations without enlarging the neutrino sector, by introducing CPT violating Dirac masses for…
