Abstract

Precision measurement of the stop mass at the ILC is done in a method based on cross-sections measurements at two different center-of-mass energies. This allows to minimize both the statistical and systematic errors. We obtain a much better stop mass precision than in previous studies In the framework of the MSSM, a light stop is studied in its decay into a charm jet and a neutralino, the Lightest Supersymmetric Particle, as a candidate of dark matter. This takes place in the co-annihilation region, namely, for a small stop-neutralino mass difference.
