Probing the top-quark width through ratios of resonance contributions of $e^{+} e^{-} \to W^{+} W^{-} b b ˉ$

Stefan Liebler, Gudrid Moortgat-Pick, Andrew S. Papanastasiou

We exploit offshell regions in the process $e^{+} e^{-} \to W^{+} W^{-} b b ˉ$ to gain access to the top-quark width. Working at next-to-leading order in QCD we show that carefully…

Resummation and Matching of $b$ -quark Mass Effects in $b b ˉ H$ Production

Marco Bonvini, Andrew S. Papanastasiou, Frank J. Tackmann

We use a systematic effective field theory setup to derive the $b b ˉ H$ production cross section. Our result combines the merits of both fixed 4-flavor and 5-flavor schemes. It…
