24 Apr 1997 | Journal: | Nucl.Phys. B507 (1997) 553-570 | Subject: | hep-th hep-ph | Abstract: | We investigate compactifications of M-theory from $11 o 5 o 4$ dimensions and discuss geometrical properties of 4-d moduli fields related to the structure of 5-d theory. We study supersymmetry breaking by compactification of the fifth dimension and find that an universal superpotential is generated for the axion-dilaton superfield $S$. The resulting theory has a vacuum with $=1$, zero cosmological constant and a gravitino mass depending on the fifth radius as $m_{3/2} sim R_5^{-2}/M_{Pl}$. We discuss phenomenological aspects of this scenario, mainly the string unification and the decompactification problem. | Source: | arXiv, hep-th/9704177 | Services: | Forum | Review | PDF | Favorites |
