Architectural choices for the Columbia 0.8 Teraflops machine

Igor V. Arsenin

We discuss the hardware design choices made in our 16K-node 0.8 Teraflops supercomputer project, a machine architecture optimized for full QCD calculations. The efficiency of the c…

K^0--\bar{K}^0 mixing in full lattice QCD

Weonjong Lee, Markus Klomfass

There are at least two methods to calculate with staggered fermions: one is the two spin trace formalism and the other is the one spin trace formalism. We have performed nu…

Critical Behavior of the chiral condensate at the QCD phase transition

Shailesh Chandrasekharan

We study the critical behavior of the chiral condensate near the QCD phase transition in the background of two fixed light dynamical (sea) quarks. We study the condensate for $5.24…

Hadron masses on a 16^3 x 40 lattice at β= 5.7

Dong Chen

We report on the hadron mass spectrum obtained on a 16^3 x 40 lattice in full QCD at β= 5.7 using two flavors of staggered fermions with m a = 0.01. We study the effective mass pla…

Observation of Target Electron Momentum Effects in Single-Arm Møller Polarimetry

M. Swartz, H. R. Band, F. J. Decker +11

In 1992, L.G. Levchuk noted that the asymmetries measured in Møller scattering polarimeters could be significantly affected by the intrinsic momenta of the target electrons. This e…

One Spin Trace Formalism for

Weonjong Lee, Markus Klomfass

It has been known for some time that there are two methods to calculate with staggered fermions: one is the two spin trace formalism and the other is the one spin trace for…

Model-Independent Comparison of Direct vs. Indirect Detection of Supersymmetric Dark Matter

Marc Kamionkowski, Kim Griest, Gerard Jungman +1

We compare the rate for elastic scattering of neutralinos from various nuclei with the flux of upward muons induced by energetic neutrinos from neutralino annihilation in the Sun a…

Bubble Nucleation Rate In Fourth-Order Gravity

Yue Hu

We calculate the bubble nucleation rate in a fourth-order gravity theory whose action contains an term, under the thin-wall approximation, by two different methods. First the…

Flavor-Parity Breaking in the NJL Model with Wilson Fermions

K. M. Bitar, P. M. Vranas

The Nambu--Jona-Lasinio model is chirally symmetric. Addition of a Wilson term explicitly breaks this symmetry and leaves the model with a remaining parity-flavor symmetry. In the…

The Box Graph In Superstring Theory

E. D'Hoker, D. H. Phong

In theories of closed oriented superstrings, the one loop amplitude is given by a single diagram, with the topology of a torus. Its interpretation had remained obscure, because it…

Polarized Bhabha Scattering and a Precision Measurement of the Electron Neutral Current Couplings

the SLD Collaboration

We present the first measurement of the left-right asymmetry in Bhabha scattering with a polarized electron beam. The effective electron vector and axial vector couplings to the Z0…

Aligning Noisy Parallel Corpora Across Language Groups : Word Pair Feature Matching by Dynamic Time Warping

Pascale Fung, Kathleen McKeown

We propose a new algorithm called DK-vec for aligning pairs of Asian/Indo-European noisy parallel texts without sentence boundaries. DK-vec improves on previous alignment algorithm…

Vortices and sound waves in superfluids

Kimyeong Lee

We consider the dynamics of vortex strings and sound waves in superfluids in the phenomenological Landau-Ginzburg equation. We first derive the vortex equation where the velocity o…

Signatures of Bulge Triaxiality from Kinematics in Baade's Window/

HongSheng Zhao, D. N. Spergel, R. M. Rich

We study a sample of 62 Baade's Window (1,-4) K giants that have published proper motions, radial velocity and metallicity. We construct the velocity ellipsoids for the metal rich…

Perturbative versus Lattice QCD Energy Density Correlators at High Temperatures

Dirk H. Rischke, Miklos Gyulassy

Correlators of magnetic and electric field energy density are investigated for SU() gauge theory at high temperatures . At separations the correlators are shown…

Instabilities of Magnetically Charged Black Holes

S. Alexander Ridgway, Erick J. Weinberg

The stability of the magnetically charged Reissner-Nordstrom black hole solution is investigated in the context of a theory with massive charged vector mesons. By exploiting the sp…
