Quenched results on $B$ Mesons with NRQCD

TL;DR

This paper presents preliminary quenched lattice QCD results for B meson spectrum and decay constants using NRQCD and static formulations, including $O(1/M_Q)$ corrections, on a $16^3\times48$ lattice.

Contribution

It provides the first quenched results for B meson properties using both NRQCD and static approaches with systematic inclusion of $O(1/M_Q)$ terms.

Findings

Consistent results with NRQCD and static formulations.

Inclusion of $O(1/M_Q)$ terms improves accuracy.

Preliminary spectrum and decay constant estimates.

Abstract

Preliminary results on spectrum and decay constant of $B$ mesons from a quenched simulation at $\beta = 6.0$ on an $16^3\times48$ lattice are discussed. The heavy quark has been implemented using both an NRQCD and the static formulation, the light one with a clover improved Wilson formulation. Both the NRQCD Hamiltonian and the heavy-light current consistently include terms of $O(1/M_{Q})$, the inverse heavy quark mass.
