Indirect Leptoquark Searches at Polarized Lepton Colliders
  We examine the utility of employing polarized lepton (electron and muon) beams to perform indirect searches for scalar leptoquarks. We find that polarization can extend the reach in excluding leptoquark masses for both $e^+e^-$ and $\mu^+\mu^-$ machines. Polarization can also provide a diagnostic tool for determining leptoquark couplings.
