Improvement of Renormalization-Scale Uncertainties Within Empirical Determinations of the b-Quark Mass

M. R. Ahmady, V. Elias, A. Squires +2

Accurate determinations of the MS-bar b-quark mass $m_b(m_b)$ from $\sigma (e^{+}{e}^{-}\to \mathrm{hadrons})$ experimental data currently contain three comparable sources of uncertainty; the expe…
