Description
In this talk, we will see that for a spontaneously broken SO(N) global symmetry, there is an infinite class of radiatively stable pseudo-Nambu-Goldstone potentials: the Gegenbauer Polynomials. The “Gegenbauer Higgs” and “Gegenbauer’s Twin” scenarios are significantly less fine-tuned than their pNGB Higgs counterpart. These scenarios require relatively small values of the quotient (g*/yt)^2, suggesting that their UV-completion may be a perturbative theory. A compelling candidate for such a UV-completion is the Supersymmetric Gegenbauer’s Twin presented in this work.
