One constraint to kill them all?
Luca Di Luzio, Matthew Kirk, Alexander Lenz
Many new physics models that explain the intriguing anomalies in the -quark flavour sector are severely constrained by -mixing, for which the Standard Model prediction and…
Astrophobic Axions
Luca Di Luzio, Federico Mescia, Enrico Nardi +2
We propose a class of axion models with generation dependent Peccei-Quinn charges for the known fermions that allow to suppress the axion couplings to nucleons and electrons. Astro…
Window for preferred axion models
Luca Di Luzio, Federico Mescia, Enrico Nardi
We discuss phenomenological criteria for defining "axion windows", namely regions in the parameter space of the axion-photon coupling where realistic models live. Currently, the bo…
Accidental Peccei-Quinn symmetry protected to arbitrary order
Luca Di Luzio, Enrico Nardi, Lorenzo Ubaldi
A gauge theory for a scalar multiplet transforming in the bi-fundamental representation preserves, for , an accidental symmetry…
Maxi-sizing the trilinear Higgs self-coupling: how large could it be?
Luca Di Luzio, Ramona Gröber, Michael Spannowsky
In order to answer the question on how much the trilinear Higgs self-coupling could deviate from its Standard Model value in weakly coupled models, we study both theoretical and ph…
