目前的质量限制使得下一代线性e + e对撞机有可能产生大量的夸克。本文探讨了在这种对撞机上精确研究夸克质量的前景。我们假设夸克比胶子轻，并讨论了直接和级联衰变两种情况。通过利用直线e + e对撞机的清洁环境和偏振光束，我们发现在很大一部分参数空间中可以在几个GeV的水平上确定方克质量。
Current mass limits allow the possibility that squarks may be produced in large numbers at the next generation of linear e + e colliders. In this paper we investigate the prospects for precision studies of squark masses at such colliders. We assume that squarks are lighter than gluinos, and discuss both direct and cascade decay scenarios. By exploiting the clean environment and polarizable beams of linear e + e colliders, we nd that squark mass determinations at the level of a few GeV are possible in a large part of the parameter space.
