Sfermion Pair Production at $\mu^+ \mu^-$ Colliders
  We discuss pair production of stops, sbottoms, staus and tau--sneutrinos at a $\mu^+ \mu^-$ collider. We present the formulae for the production cross sections and perform a detailed numerical analysis within the Minimal Supersymmetric Standard Model. In particular, we consider sfermion production near $\sqrt{s} = m_{H^0}$ and $\sqrt{s} = m_{A^0}$.
