One-loop stabilization of the fuzzy four-sphere via softly broken SUSY

Abstrakt

We describe a stabilization mechanism for fuzzy S-N(4) in the Euclidean JIB matrix model due to vacuum energy in the presence of a positive mass term. The one-loop effective potential for the radius contains an attractive contribution attributed to supergravity, while the mass term induces a repulsive contribution for small radius due to SUSY breaking. This leads to a stabilization of the radius. The mechanism should be pertinent to recent results on the genesis of 3+1-dimensional space-time in the Minkowskian IIB model.
