Small Visible Energy Scalar Top Iterative Discriminant Analysis
  Light scalar top quarks with a small mass difference with respect to the neutralino mass are of particular cosmological interest. This study uses an Iterative Discriminant Analysis method to optimize the expected selection efficiency at a International Linear Collider (ILC).
