The effects of topological charge change in heavy ion collisions: "Event by event P and CP violation"

Dmitri E. Kharzeev, Larry D. McLerran, Harmen J. Warringa

Quantum chromodynamics (QCD) contains field configurations which can be characterized by a topological invariant, the winding number Q_w. Configurations with nonzero Q_w break the…

Universal properties of bulk viscosity near the QCD phase transition

F. Karsch, D. Kharzeev, K. Tuchin

We extract the bulk viscosity of hot quark-gluon matter in the presence of light quarks from the recent lattice data on the QCD equation of state. For that purpose we extend the su…

On the Relation Between Mechanisms for Single-Transverse-Spin Asymmetries

Yuji Koike, Werner Vogelsang, Feng Yuan

Recent studies have shown that two widely-used mechanisms for single-transverse-spin asymmetries based on either twist-three contributions or on transverse-momentum-dependent (Sive…

CNI polarimetry with Helium 3

T. L. Trueman

By making use of previous analysis of CNI for pp and pC scattering, the spin-flip factor for np scattering is determined as a function of energy and then used to calculate the p He…

On Direct Verification of Warped Hierarchy-and-Flavor Models

Hooman Davoudiasl, Thomas G. Rizzo, Amarjit Soni

We consider direct experimental verification of warped models, based on the Randall-Sundrum (RS) scenario, that explain gauge and flavor hierarchies, assuming that the gauge fields…
