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…
