====== TTP07-12 Running of $\alpha_s$ and $m_b$ in the MSSM ======
 
 
   <hidden TTP07-12  Running of $\alpha_s$ and $m_b$ in the MSSM > A consistent evolution of the strong coupling constant $\alpha_s$ from
 $M_Z$ to the GUT scale is presented, involving three-loop running and
 two-loop decoupling. The two-loop transition from the MS- to the
 DR-scheme is properly taken into account.  In the second part of
 the paper, the bottom quark mass in the DR- scheme at the
 electroweak/SUSY scale is evaluated with four-loop accuracy.
 We find that the three-loop effects are comparable to the experimental
 uncertainty both for $\alpha_s$ and $m_b$.
