Description
There is a novel way to achieve the gauge coupling unification with an unbroken hidden U(1) symmetry. In this case, a kinetic mixing and a hidden coupling are required to be large. Consequently, the axion-photon coupling is significantly enhanced if one employs the Peccei-Quinn solution to the strong CP-problem. We show that this enhanced coupling can be tested in various future experiments.
