    abstract = "We calculate the contribution of a superstring-inspired heavy diquark to
the four-jet rate in e+e- collisions. We find that Z-decay data with
charm-quark tagging, corresponding to an integrated luminocity of 20-100
pb-1, will set a bound of 50-60 GeV on the diquark mass. We argue that
this is a rather model-independent result."
