Lifetime top quark

Following up on elementary charge, I read here that the top quark with charge 2/3 e can exist outside confinement. You write less than 5 × 10−25 sec. The question that pops up here is how much less? Anyway, it seems to me that for all practical purposes e is the smallest charge outside confinement, and that the free top quark may be mentioned as an exotic exception to the rule.--Paul Wormer 08:40, 12 November 2007 (CST)
