This paper reviews recent advances in lattice QCD calculations of heavy quark properties, focusing on decay constants, form factors, B-mixing, and non-perturbative b-quark mass determination using HQET.

Contribution

It presents new non-perturbative results for the b-quark mass and discusses the application of HQET on the lattice for heavy quark phenomenology.

Findings

Accurate lattice determinations of decay constants and form factors.

Non-perturbative b-quark mass including 1/m_b corrections.

Insights into B- B mixing from lattice QCD.

Abstract

I review recent progresses in heavy quarks physics on the lattice. I focus on decay constants and form factors relevant for the extraction of CKM matrix elements from experimental data. B-\bar{B} mixing is also discussed. In the last part of the paper I describe phenomenological applications of Heavy Quark Effective Theory (HQET) on the lattice, presenting in some detail the recent non-perturbative determination of the b-quark mass including O(1/m_b) corrections.
