# All-orders behaviour and renormalons in top-mass observables

25 Oct 2018 Ravasio Silvia Ferrario Nason Paolo Oleari Carlo

We study a simplified model of top production and decay, consisting in a virtual vector boson $W^*$ decaying into a massive-massless $t$-$\bar{b}$ quark-antiquark pair. The top has a finite width and further decays into a stable vector boson $W$ and a $b$ quark... (read more)
