Journal Article

We propose a mechanism that allows for sizeable flavour violation in quark-lepton currents, while suppressing flavour changing neutral currents in quark-quark and lepton-lepton sectors. The mechanism is applied to the recently proposed “4321” renorma... Read More about Maximal flavour violation: a Cabibbo mechanism for leptoquarks.

Axion mass prediction from minimal grand unification (2018)
Journal Article
Di Luzio, L., Ringwald, A., & Tamarit, C. (2018). Axion mass prediction from minimal grand unification. Physical Review D, 98(9), Article 095011. https://doi.org/10.1103/physrevd.98.095011

We propose a minimal realization of the Peccei-Quinn mechanism in a realistic SU(5) model, where the axion mass is directly connected to the grand unification scale. Accounting for constraints from proton decay, collider searches and gauge coupling u... Read More about Axion mass prediction from minimal grand unification.

Astrophobic Axions (2018)
Journal Article

We propose a class of axion models with generation-dependent Peccei-Quinn charges for the known fermions that allow one to suppress the axion couplings to nucleons and electrons. Astrophysical limits are thus relaxed, allowing for axion masses up to... Read More about Astrophobic Axions.

Updated Bs -mixing constraints on new physics models for b→sℓ+ℓ− anomalies (2018)
Journal Article
Di Luzio, L., Kirk, M., & Lenz, A. (2018). Updated Bs -mixing constraints on new physics models for b→sℓ+ℓ− anomalies. Physical Review D, 97(9), Article 095035. https://doi.org/10.1103/physrevd.97.095035

Many new physics models that explain the intriguing anomalies in the b-quark flavor sector are severely constrained by Bs mixing, for which the Standard Model prediction and experiment agreed well until recently. The most recent Flavour Lattice Avera... Read More about Updated Bs -mixing constraints on new physics models for b→sℓ+ℓ− anomalies.
