摘要
We extend the Standard Model gauge group by a a gauged U(1)(R) R-symmetry or a gauged U(1)'. The requirement of cancellation of anomalies is very constraining but can be achieved by adding three or four hidden-sector fields which are Standard Model singlets. The U(1)(R) or U(1)' quantum numbers of these singlets are usually large producing a non-renormalisable superpotential with a high power in the singlet fields. We have minimized the supergravity scalar potential and have found solutions where the vacuum expectation values of all hidden-sector singlet fields are less than the Planck mass <z(m)> = O(M(Pl)/10), This produces the small supersymmetry scale of order the weak scale from only the Planck scale. The mu problem is simultaneously solved in this manner.
