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…
