Imperfect Axions

Luca Di Luzio

In this contribution, I'll discuss two classes of effects--additional sources of CP violation and PQ breaking--that offer a slightly different take on axion physics. Both are tied…

Hunting for a 17 MeV particle coupled to electrons

Luca Di Luzio, Paride Paradisi, Nudzeim Selimovic

We discuss a set of precision observables that can probe the existence of a light particle coupled to electrons in the mass range of 1-100 MeV. As a case study, we consider the…

High-quality Peccei-Quinn symmetry from the interplay of vertical and horizontal gauge symmetries

Luca Di Luzio, Giacomo Landini, Federico Mescia +1

We explore a class of axion models where an accidental Peccei-Quinn (PQ) symmetry automatically emerges from the interplay of vertical (grand-unified) and horizonta…

The physics case of a 3 TeV muon collider stage

Jorge De Blas, Dario Buttazzo, Rodolfo Capdevilla +131

In the path towards a muon collider with center of mass energy of 10 TeV or more, a stage at 3 TeV emerges as an appealing option. Reviewing the physics potential of such muon coll…

Muon Collider Physics Summary

Chiara Aimè, Aram Apyan, Mohammed Attia Mahmoud +122

The perspective of designing muon colliders with high energy and luminosity, which is being investigated by the International Muon Collider Collaboration, has triggered a growing i…

An exceptionally light axion: Strong CP and Dark Matter

Pablo Quilez, Luca Di Luzio, Belen Gavela +1

We explore whether the axion which solves the strong CP problem can naturally be much lighter than the canonical QCD axion. The symmetry proposed by Hook, with $\ma…
