10 Sep 2001 | | Journal: | JHEP 0207 (2002) 020 | | Subject: | hep-th hep-ph | | Abstract: | We present examples of four dimensional, non-supersymmetric field theories in which ultraviolet supersymmetry breaking effects, such as bose-fermi splittings and the vacuum energy, are suppressed by $(alpha/4 pi)^{N}$, where $alpha$ is a weak coupling factor and $N$ can be made arbitrarily large. The particle content and interactions of these models are conveniently represented by a graph with sites and links, describing the gauge theory space structure. While the theories are supersymmetric ``locally’’ in theory space, supersymmetry can be explicitly broken by topological obstructions. | | Source: | arXiv, hep-th/0109082 | | Services: | Forum | Review | PDF | Favorites | |
