Özet

We calculate the one-loop flavor changing neutral current top quark decay t -> cgg in the standard model. We demonstrate that the rate for t -> cgg exceeds the rate for a single gluon emission t -> cg by about 2 orders of magnitude, while the rate for t -> cq (q) over bar q=u is slightly smaller than for t -> cg.
