英文摘要	In supersymmetry, the flavor mixing between top-squark (stop) and charm-squark (scharm) induces the flavor-changing neutral-current (FCNC) stop decay (t) over tilde (1)-->c (χ) over tilde (0)(1). Searching for this decay serves as a probe of soft supersymmetry breaking parameters. Focusing on the stop pair production followed by the FCNC decay of one stop and the charge-current decay of the other stop, we investigate the potential of detecting this FCNC stop decay at the Fermilab Tevatron, the CERN Large Hadron Collider and the next-generation e(+)e(-) linear collider. We find that this decay may not be accessible at the Tevatron, but could be observable at the Large Hadron Collider and the linear collider with high sensitivity for some part of parameter space.
