An unquenched lattice QCD calculation of the mass of the bottom quark

TL;DR

This paper presents a lattice QCD calculation of the bottom quark mass using dynamical simulations with clover quarks, achieving a precise determination with quantified uncertainties.

Contribution

It provides a new unquenched lattice QCD determination of the bottom quark mass at a fixed lattice spacing with low sea quark masses.

Findings

Bottom quark mass m_b(m_b) = 4.25(2)(11) GeV

First error is statistical, second is systematic

Calculation done at fixed lattice spacing with sea quark masses as low as half the strange quark mass

Abstract

We compute the b quark mass from dynamical lattice QCD with clover quarks. The calculation is done at a fixed lattice spacing with sea quark masses as low as half the strange quark mass. Our final result is m_b(m_b} = 4.25(2)(11) GeV, where the first error is statistical and the last error is the systematic uncertainty.
