Three-loop soft function for heavy-to-light quark decays
Robin Brüser, Ze Long Liu, Maximilian Stahlhofen
We compute the 1-jettiness soft function for the decay of a heavy quark into a light quark jet plus colorless particles at three-loop order in soft-collinear effective theory. The…
Matter dependence of the four-loop QCD cusp anomalous dimension: from small angles to all angles
Robin Brüser, Andrey Grozin, Johannes M. Henn +1
We compute the fermionic contributions to the cusp anomalous dimension in QCD at four loops as an expansion for small cusp angle. As a byproduct we also obtain the respective terms…
Subleading Regge limit from a soft anomalous dimension
Robin Brüser, Simon Caron-Huot, Johannes M. Henn
Wilson lines capture important features of scattering amplitudes, for example soft effects relevant for infrared divergences, and the Regge limit. Beyond the leading power approxim…
