All-orders behaviour and renormalons in top-mass observables
Abstract We study a simplified model of top production and decay, consisting in a virtual vector boson W * decaying into a massive-massless t- b ¯ $$ \overline{b} $$ quark-antiquark pair. The top has a finite width and further decays into a stable vector boson W and a b quark. We then consider the e...
