Beyond the Narrow-Width Limit for Off-Shell and Boosted Differential Top Quark Decays
André H. Hoang, Simon Plätzer, Christoph Regner +1
The standard approaches for describing top quark production and its decay dynamics are currently mostly either based on the narrow-width (NW) limit or on off-shell fixed-order calc…

Towards Colour Flow Evolution at Two Loops
Simon Plätzer, Ines Ruffa
We calculate the two-loop and one-loop/one-emission contributions required for soft gluon evolution at the next-to-leading order. The colour structures are expressed in the colour…
