Abstract

The value of the bottom quark mass at Q=M_Z in the DR scheme is an important input for the analysis of supersymmetric models with a large value of tan\ensuremathβ. Conventionally, however, the running bottom quark mass extracted from experimental data is quoted in the MS scheme at the scale Q=m_b. We describe a two loop procedure for the conversion of the bottom quark mass from the MS to DR scheme. The Particle Data Group value m_b^MS(m_b^MS)=4.2\ifmmode±\else\textpm\fi0.2GeV corresponds to a range of 2.65--3.03 GeV for m_b^DR(M_Z).
