Contribution
It introduces a novel kappa symmetric WZNW model for OSp(2|2), incorporating the supergroup's structure into the AdS3xS1 background.
Findings
The model exhibits chiral current conservation.
Right-moving modes include bosons and fermions.
Left-moving modes contain only bosons.
Abstract
We construct a kappa symmetric WZNW model for the OSp(2|2) supergroup, whose bosonic part is AdS3xS1 space. The field equation gives the chiral current conservation and the right/left factorization is shown after the kappa symmetry is fixed. The right-moving modes contain both bosons and fermions while the left-moving modes contain only bosons.
