Quenched Heavy-Light Decay Constants

TL;DR

This paper reports on decay constants calculated in a quenched lattice QCD simulation, comparing propagating quarks and static theory at a specific lattice setup, to test heavy quark symmetry predictions.

Contribution

It provides decay constants from quenched simulations using both propagating and static quarks, testing heavy quark symmetry scaling laws.

Findings

Results support heavy quark symmetry predictions

Decay constants obtained at $eta=6.2$ on $24^3 imes48$ lattice

Comparison between propagating and static quark results

Abstract

We present decay constants from a quenched simulation using both propagating quarks and the static theory at $\beta=6.2$ on $24^3\times48$. The results using propagating quarks are used to test scaling laws predicted by the heavy quark symmetry.
