Perturbative running of the topological angles
Alessandro Valenti, Luca Vecchi
We argue that in general renormalizable field theories the topological angles may develop an additive beta function starting no earlier than 2-loop order. The leading expression is…
Grand Color Axion
Alessandro Valenti, Luca Vecchi, Ling-Xiao Xu
We present a model that solves the strong CP problem via an axion parametrically heavier than the standard one. Within this picture the Standard Model quarks are embedded into a la…
Spontaneous CP violation
Alessandro Valenti
Models of spontaneous CP violation can solve the Strong CP problem without the need of an anomalous Peccei-Quinn symmetry. In this work we review the Nelson-Barr approach, quantify…
High-energy frontier of the muon g-2 at a muon collider
Paride Paradisi, Olcyr Sumensari, Alessandro Valenti
The long-standing muon g-2 anomaly can be explained by heavy new physics particles through chirally enhanced contributions. It has been recently proposed that a muon collider runni…
