Towards a Consistent SUSY QFT in Extra Dimensions
Abstract
We consider N=1 SUSY gauge theory in six dimensions in components and show that provided the Dynkin indices of the matter fields representations satisfy the relation Σ T(R)= C2(G), the gauge sector is completely one-loop finite. In the matter sector the UV divergences form several invariant structures some of which are cancelled in physical amplitudes. Thus, the theory which is in general non-renormalizable may be consistent and even finite. Consequences for the SUSY GUT models in the bulk are briefly discussed.
