چکیده    It is widely thought that increasing bounds on the gluino mass, which feeds down to the stop mass through renormalization group running, are making a light stop increasingly unlikely. here we present a counter-example. we examine the case of the minimal composite supersymmetric standard model which has a light composite stop. the large anomalous dimension of the stop from strong dynamics pushes the stop mass toward a quasi-fixed point in the infrared, which is smaller than standard estimates by a factor of a large logarithm. the gluino can be about three times heavier than the stop, which is comparable to hierarchy achieved with supersoft dirac gluino masses. thus, in this class of models, a heavy gluino is not necessarily indicative of a heavy stop.
