Polychromatic Grand Unification
Abstract
The possibility of achieving a gauge coupling grand unification by increasing the QCD degrees of freedom at higher energies is investigated. When confronted with precision low-energy data, the generic weak-mixing angle relation sin2(thetaW) = N/2(N+1) requires N=7 colors at the GUT scale MU ~ 1017 GeV. With the exclusive addition of light Higgs doublets to the standard model particle content, such a unification may also occur if N=5 at MU ~ 1016 GeV.
