Endpoint Factorization for Semileptonic Decays of Boosted and Resonant Off-Shell Top Quarks with a Large-Radius Bottom Jet
Andre H. Hoang, Christoph Regner
We derive a factorization formula for boosted double resonant top-antitop pair production in annihilation with a semileptonic top quark decay in the phase space region whe…

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…

On the Discrepancy between the FOPT and CIPT Approaches for Hadronic Tau Spectral Function Moments
Andre H. Hoang, Christoph Regner
The discrepancy between the FOPT and CIPT approaches for hadronic spectral function moments constitutes the major theoretical uncertainty for strong coupling determinations fro…
