The unitarity of a spontaneously broken SU(2) theory using unitary-gauge diagrams
Jochem Kip, Ronald Kleiss
A spontaneously broken SU(2) theory is the simplest generalization of the Abelian Higgs model, containing three equally massive vector bosons and a single Higgs scalar. A strictly…
Collinear Electroweak Radiation in Antenna Parton Showers
Ronald Kleiss, Rob Verheyen
We present a first implementation of collinear electroweak radiation in the Vincia parton shower. Due to the chiral nature of the electroweak theory, explicit spin dependence in th…
Final-state QED Multipole Radiation in Antenna Parton Showers
Ronald Kleiss, Rob Verheyen
We present a formalism for a fully coherent QED parton shower. The complete multipole structure of photonic radiation is incorporated in a single branching kernel. The regular on-s…
Amplitudes, recursion relations and unitarity in the Abelian Higgs Model
Ronald Kleiss, Oscar Boher Luna
The Abelian Higgs model forms an essential part of the electroweak standard model: it is the sector containing only Z and Higgs bosons. We present a diagram-based proof of the tree…
Competing Sudakov Veto Algorithms
Ronald Kleiss, Rob Verheyen
We present a way to analyze the distribution produced by a Monte Carlo algorithm. We perform these analyses on several versions of the Sudakov veto algorithm, adding a cutoff, a se…
No Landau-Yang in QCD
W. Beenakker, R. Kleiss, G. Lustermans
The Landau-Yang theorem, forbidding transition amplitudes between a massive spin-1 particle and two photons, is widely assumed to apply to other massless spin-1 particles. We show…
