The top quark interacts primarily by the strong interaction but can only decay through the weak force. It decays almost exclusively to a W boson and a bottom quark, but it can decay also into a strange quark, and on the rarest of occasions, into a down quark. The Standard Model predicts its mean lifetime to be roughly {val|5|e=-25|u=s}. This is ab...
