Scale symmetry breaking and generation of mass at quantum critical points
Charlie Cresswell-Hogg, Daniel F. Litim
We study an asymptotically free theory of relativistic Dirac fermions and a real scalar field coupled by Yukawa and scalar self-interactions in three dimensions using functiona…
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…
Asymptotic Safety Guaranteed at Four Loop
Daniel F. Litim, Nahzaan Riyaz, Emmanuel Stamou +1
We investigate a family of four-dimensional quantum field theories with weakly interacting ultraviolet fixed points up to four loop order in perturbation theory. Key new ingredient…
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…
