Perturbative Matching of the NRQCD Heavy-Light Axial Current

A one-loop matching calculation between Lattice NRQCD and full QCD for the heavy-light axial current is described and the effects on f_B are discussed.Comment: Talk presented at Lattice '97, Edinburgh, July 1997. 3 LaTeX pages plus 2 postscript figures. Uses espcrc2.st

Design and Experimental Validation of a Ducted Counter-rotating Axial-flow Fans System

An experimental study on the design of counter-rotating axial-flow fans was carried out. The fans were designed using an inverse method. In particular, the system is designed to have a pure axial discharge flow. The counter-rotating fans operate in a ducted-flow configuration and the overall performances are measured in a normalized test bench. The rotation rate of each fan is independently controlled. The relative axial spacing between fans can vary from 17% to 310%. The results show that the efficiency is strongly increased compared to a conventional rotor or to a rotor-stator stage. The effects of varying the rotation rates ratio on the overall performances are studied and show that the system has a very flexible use, with a large patch of high efficient operating points in the parameter space. The increase of axial spacing causes only a small decrease of the efficiencyComment: accepted in Journal of Fluid Engineerin

Semileptonic B Decays from an NRQCD/D234 Action

Semileptonic B decays are studied on quenched anisotropic lattices using Symanzik improved glue, NRQCD heavy quark and D234 light quark actions. We employ constrained fits to extract ground state contributions to two- and three-point correlators. Results for the B --> pi, l nubar decay form factors are compared with previous lattice results. We find that our systematic errors (excluding quenching errors) are dominated by chiral extrapolation uncertainties.Comment: Lattice2002(Heavy quark physics

QCD on 2+2 anisotropic lattices

We discuss the implementation of QCD on 2+2 anisotropic lattices. Technical details regarding the choice of the action as well as perturbative and non-perturbative improvement are analyzed. The physical applications of the program are presented.Comment: 3 pages, 1 figure. Talk given by G. Burgio at Lattice02, MIT. To appear on Nucl. Phys. B (proc. Suppl.
