QCD Thermodynamics at and 12
the HEMCGC, MILC Collaborations
We present results from studies of high temperature QCD with two flavors of Kogut-Susskind quarks on lattices at a quark mass of and on $24^3\times 12…
Monte Carlo and Renormalization Group Effective Potentials in Scalar Field Theories
J. R. Shepard, V. Dmitrašinović, J. A. McNeil
We study constraint effective potentials for various strongly interacting theories. Renormalization group (RG) equations for these quantities are discussed and a heuristic de…
Exponential Tails in the Centroid Velocity Distributions of Star-Forming Regions
Mark S. Miesch, John M. Scalo
Probability density functions (pdfs) of emission line centroid (line-of-sight, intensity-weighted average) velocities are presented for several densely sampled molecular…
Towards a perfect fixed point action for SU(3) gauge theory
T. DeGrand, A. Hasenfratz, P. Hasenfratz +2
We present an overview of the construction and testing of actions for SU(3) gauge theory which are approximate fixed points of renormalization group equations (at $β\rightarrow \in…
Defect-Mediated Stability: An Effective Hydrodynamic Theory of Spatio-Temporal Chaos
Carson C. Chow, Terence Hwa
Spatiotemporal chaos (STC) exhibited by the Kuramoto-Sivashinsky (KS) equation is investigated analytically and numerically. An effective stochastic equation belonging to the KPZ u…
Preliminary heavy-light decay constants from the MILC collaboration
C. Bernard, T. Blum, A. De +10
Preliminary results from the MILC collaboration for , , , and their ratios are presented. We compute in the quenched approximation at , 6.0 and…
