摘要：

We study the possibility of discovering or excluding a light top squark (stop) <(t)over tilde (1)> based on top quark decays in the <t(t)over bar> events produced at the Fermilab Tevatron. In particular, we consider the Minimal Supersymmetric Standard Model with the sparticle spectrum m(chi 1)+/- + m(b), M(W) + m(chi 1)(0) + m(b) > m((t) over tilde1$) > m(chi 1)(0) + m(c), where chi(1)(0) is the lightest neutralino, so that t --> <(t)over tilde (1)> chi(1)(0) and <(t)over tilde (1)> --> c chi(1)(0). All other sparticle masses are assumed to be heavier than m(t). Such a spectrum seeks to explain the experimental values of alpha(s)(M(Z)(2)), R(b) and A(LR) Obtained from LEP/SLC data. We find that the prospect to observe a light stop via this channel at the Tevatron is very promising.
