UV-complete Gauged Anomaly-free U(1) Froggatt-Nielsen Model
Johan Rathsman, Felix Tellander
We investigate the possibility of understanding all fermion masses and mixings within a gauged Froggatt-Nielsen framework. Continuing the work from [J. Rathsman and F. Tellander, P…
Tropical Feynman integration in the physical region
Michael Borinsky, Henrik J. Munch, Felix Tellander
The software feyntrop for direct numerical evaluation of Feynman integrals is presented. We focus on the underlying combinatorics and polytopal geometries facilitating these method…
Symbol Alphabets from the Landau Singular Locus
Christoph Dlapa, Martin Helmer, Georgios Papathanasiou +1
We provide evidence through two loops, that rational letters of polylogarithmic Feynman integrals are captured by the Landau equations, when the latter are recast as a polynomial o…
Tropical Feynman integration in the Minkowski regime
Michael Borinsky, Henrik J. Munch, Felix Tellander
We present a new computer program, , which uses the tropical geometric approach to evaluate Feynman integrals numerically. In order to apply this approach in the…
