Abstract
We compute the exact two‐loop matching coefficient for the bottom‐quark mass mb, within the Minimal Supersymmetric Standard Model (MSSM), taking into account O(αs2) contributions from the Supersymmetric Quantum Chromodynamics (SQCD). We find that the three‐loop order corrections to the running bottom‐quark mass exceed the uncertainty due to the current experimental accuracy. They can reach up to 30% from the tree‐level mb, for models with large values of tan β and relatively light SUSY mass scale.
