Аннотация доклада:
We study the pair production of scalar top quarks (stop, ~ t 1 ) in e + e collisions with the subsequent decay of the top squarks in to b -quarks and c harginos ~ t 1 ! b ~ 1 . W e simulate this process by using PYTHIA6 for a beam energy 2 E e beam = p s ee = 500 GeV. A set of criteria for physical variables is proposed which provides a good separation of stop signal events from top quark pair production which is the main background. These criteria allow us to reconstruct the mass of the top squark with two years of ILC running pro vided that the neutralino mass is known
