ALPs, the on-shell way
Enrico Bertuzzo, Christophe Grojean, Gabriel M. Salla
We study how the coupling between axion-like particles (ALPs) and matter can be obtained at the level of on-shell scattering amplitudes. We identify three conditions that allow us…
Hilbert series for ALP EFTs
Christophe Grojean, Jonathan Kley, Chang-Yuan Yao
Axions and axion-like particles (ALPs) are ubiquitous in popular attempts to solve supercalifragilisticexpialidocious puzzles of Nature. A widespread and vivid experimental program…
Towards a Muon Collider
Carlotta Accettura, Dean Adams, Rohit Agarwal +294
A muon collider would enable the big jump ahead in energy reach that is needed for a fruitful exploration of fundamental interactions. The challenges of producing muon collisions a…
Opportunistic CP Violation
Quentin Bonnefoy, Emanuele Gendy, Christophe Grojean +1
In the electroweak sector of the Standard Model, CP violation arises through a very particular interplay between the three quark generations, as described by the Cabibbo--Kobayashi…
