Squark mass determination at a future linear collider

摘要

Present mass limits allow the possibility that squarks may be produced at future linear e(sup +)e(sup (minus)) colliders. In this talk the authors discuss the prospects for precision studies of squark masses at such a facility. Both direct and cascade decay scenarios are discussed. By exploiting the clean environment and polarizable beams of linear e(sup +)e(sup (minus)) colliders, they find that squark mass determinations at the level of a few GeV are possible for a number of regions in parameter space.
