摘要：

The value of the bottom quark mass at Q=M-Z in the (DR) over bar scheme is an important input for the analysis of supersymmetric models with a large value of tan beta. Conventionally, however, the running bottom quark mass extracted from experimental data is quoted in the (MS) over bar scheme at the scale Q=m(b). We describe a two loop procedure for the conversion of the bottom quark mass from the (MS) over bar to (DR) over bar scheme. The Particle Data Group value m(b)((MS) over bar)(m(b)((MS) over bar))=4.2+/-0.2 GeV corresponds to a range of 2.65-3.03 GeV for m(b)((DR) over bar)(M-Z).
