  1. 4. Axionless solution to the strong CP problem
    Eduardo Peinado
    13/01/2026, 11:00

    The strong CP problem in QCD remains one of the most compelling puzzles in particle physics, traditionally addressed through the Peccei–Quinn mechanism and the axion. In this talk, I will present a 2HDM extension of the Standard Model, where CP is spontaneously broken, offering a viable and testable approach to resolving the strong CP problem without invoking an axion.
