On a class of finite sigma-models and string vacua: a supersymmetric extension

Following a suggestion made by Tseytlin, we investigate the case when one replaces the transverse part of the bosonic action by an $n=2$ supersymmetric sigma-model with a symmetric homogeneous K\"ahlerian target space. As conjectured by Tseytlin, the metric is shown to be exactly known since th...

description Following a suggestion made by Tseytlin, we investigate the case when one replaces the transverse part of the bosonic action by an $n=2$ supersymmetric sigma-model with a symmetric homogeneous K\"ahlerian target space. As conjectured by Tseytlin, the metric is shown to be exactly known since the beta function is known to reduce to its one-loop value.

We demonstrate what has been conjectured by Tseytlin:i.e. the metric is shown to be exactly known since the exact expression of the beta-function reduces to its one-loop value.hep-th/9304119CPT-93-P-2879CERN-TH-6828-93CERN-TH-6828-93CPT-2879oai:cds.cern.ch:2489961993
