Description
We explore one attractive ultraviolet-violet complete extension of the Standard Model (SM) with the gauge structure $SU(5)\times Sp(2)^\prime\times SU(2)_L \times U(1)_Y^\prime$ that breaks into a technicolor (TC) sector, the QCD and $U(1)_Y$. The TC sector later confines, respecting $SU(4)/Sp(4)$ to yield the SM Higgs boson. The TC confinement and the small instanton of $Sp(2)^\prime$ altogether enhance the axion potential. Eventually, all axions in our model are far heavier than the QCD one and the strong CP problem is automatically solved.
