General vacuum stability of orbifold gauge breaking and application to asymptotic grand unification

Giacomo Cacciapaglia, Alan S. Cornell, Aldo Deandrea +4

We examine the vacuum stability of gauge symmetry breaking in five dimensions, compactified on the $S_1/({\mathbb{Z}}_2\times {\mathbb{Z}}_2^{\prime })$ orbifold. We consider $SU(N)$, $Sp(N)$,…
