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…
Critical Fermions with Spontaneously Broken Scale Symmetry
Charlie Cresswell-Hogg, Daniel F. Litim
We study relativistic fermions in three euclidean dimensions with four- and six-fermion interactions of the Gross-Neveu type. In the limit of many fermion flavors, and besides the…
Why is zero spatial curvature special?
Raul Jimenez, Ali Rida Khalife, Daniel F. Litim +2
Evidence for almost spatial flatness of the Universe has been provided from several observational probes, including the Cosmic Microwave Background (CMB) and Baryon Acoustic Oscill…
