Stability of the Higgs Potential in the Standard Model and Beyond
Tom Steudtner
The question of stability of the Higgs potential in the Standard Model is revisited employing advanced theoretical precision and recent experimental results. We show that the top m…
MaRTIn -- Manual for the "Massive Recursive Tensor Integration"
Joachim Brod, Lorenz Hüdepohl, Emmanuel Stamou +1
We present MaRTIn, an extendable all-in-one package for calculating amplitudes up to two loops in an expansion in external momenta or using the method of infrared rearrangement. Re…
Old and new anomalies in charm
Rigo Bause, Hector Gisbert, Gudrun Hiller +3
The recent LHCb determination of the direct CP asymmetries in the decays hints at a sizeable breaking of two approximate symmetries of the SM: CP and U-s…
Vacuum Stability as a Guide for Model Building
Gudrun Hiller, Tim Höhne, Daniel F. Litim +1
We explain why vector-like fermions are natural candidates to lift the Standard Model vacuum instability. Results are further discussed from the viewpoint of criticality. Several m…
ARGES -- Advanced Renormalisation Group Equation Simplifier
Daniel F. Litim, Tom Steudtner
We present the initial release of ARGES, a toolkit for obtaining renormalisation group equations in perturbation theory. As such, ARGES can handle any perturbatively renormalisable…
Model Building from Asymptotic Safety with Higgs and Flavor Portals
Gudrun Hiller, Clara Hormigos-Feliu, Daniel F. Litim +1
We perform a comprehensive search for Standard Model extensions inspired by asymptotic safety. Our models feature a singlet matrix scalar field, three generations of vector-like le…
