Spontaneous C P violation and flavor changing neutral currents in minimal SO(10)
Abstract:
We explore spontaneous CP violation in the minimal non-super-symmetric SOð10Þ grand unified
theory, with a scalar sector comprising a CP-even 45$_H$, a 126$_H$, and a complex 10$_H$. All renormalizable
couplings are real due to CP symmetry, and the Kobayashi-Maskawa phase arises solely from complex
electroweak vacuum expectation values. The model requires an additional Higgs doublet fine-tuned
below 500 GeV and constrains new Yukawa couplings, linking certain flavor-violating (FV) processes.
Future proton decay observations may reveal correlated FV decay ratios, offering insights into minimal
SO(10).
