Abstract: A bstractA very simple model is presented where all CP violation in Nature is spontaneous in origin. The CKM phase is generated unsuppressed and the strong CP problem is solved with only moderately small couplings… read more here.

Abstract: A bstractThe QCD axion is one of the most compelling solutions of the strong CP problem. There are major current efforts into searching for an ultralight, invisible axion, which is believed to be the only… read more here.

DOI: 10.1007/jhep12(2018)035

Abstract: A bstractMotivated by the intimate connection between the strong CP problem and the flavor structure of the Standard Model, we present a flavor model that revives and extends the classic mu = 0 solution to… read more here.

DOI: 10.1103/physrevd.104.075011

Abstract: We show that QCD instantons can generate large effects at small length scales in the ultraviolet in standard composite Higgs models that utilise partial compositeness. This has important implications for possible solutions of the strong… read more here.

DOI: 10.1142/s0217751x21502365

Abstract: A bonus of the framed standard model (FSM), constructed initially to explain the mass and mixing patterns of quarks and leptons, is a solution (without axions) of the strong CP problem by cancelling the theta-angle… read more here.
