Abstract：
We studied the one-loop gluino correction to the process Z→bb in the minimal supersymmetric standard model (N=1) and investigated the dependence of the process on gluino and squark masses and the effects of L-R Squark mixing.For some values of the massesunder study,the correction to the ratio of the Z→bb partial width to all hadrons' may reach 3%.
