Heavy QCD Axions at High-Energy Muon Colliders
Ravneet Bedi, Tony Gherghetta, Soubhik Kumar +2
We study the physics potential of heavy QCD axions at high-energy muon colliders. Unlike typical axion-like particles, heavy QCD axions solve the strong CP problem with phenomenolo…
Solving the strong CP problem with massless grand-color quarks
Ravneet Bedi, Tony Gherghetta, Keisuke Harigaya
We propose a solution to the strong CP problem that specifically relies on massless quarks and has no light axion. The QCD color group is embedded into a larger, simple g…
Small instanton-induced flavor invariants and the axion potential
Ravneet Bedi, Tony Gherghetta, Christophe Grojean +3
Small instantons which increase the axion mass due to an appropriate modification of QCD at a UV scale , can also enhance the effect of CP-violating operators to shift…
Enhanced EDMs from Small Instantons
Ravneet S. Bedi, Tony Gherghetta, Maxim Pospelov
We show that models in which the strong problem is solved by introducing an axion field with a mass enhanced by non-QCD UV dynamics at a scale exhibit enhanced se…
