Minimal Higher-Dimensional Extensions of the Standard Model and Electroweak Observables

Alexander Mück, Apostolos Pilaftsis, Reinhold Rückl

We consider minimal 5-dimensional extensions of the Standard Model compactified on an $S^1/Z_2$ orbifold, in which the SU(2)${}_L$ and U(1)${}_Y$ gauge fields and Higgs bosons may or m…
