Description
We present a UV-complete extension of the Standard Model based on the gauge group (SU(5)\times SU(3)c^{\prime}\times Sp(2){TC}^{\prime}\times SU(2)L\times U(1)_Y), which breaks in two steps to QCD and a technicolor sector. Three axions cancel the three (\theta)-terms. Small instantons from the confining (SU(3)_c^{\prime}) and (Sp(2){TC}^{\prime}) sectors generate axion potentials, raising their masses to the eV range---well above the QCD axion. The model includes a composite Higgs ((SU(4)/Sp(4))) yielding a 125 GeV Higgs. Anomaly cancellation is verified. This provides a concrete ``hypercolored axion'' realization with multiple heavy axions.
