Higher-spin conserved currents in supersymmetric sigma models on symmetric spaces
Young, Charles A. S.; Evans, Jonathan (2005-01-12)Local higher-spin conserved currents are constructed in the supersymmetric sigma models with target manifolds symmetric spaces $G/H$. One class of currents is based on generators of the de Rham cohomology ring of $G/H$; a ... -
Quantum, higher-spin, local charges in symmetric space sigma models
Young, Charles A. S.; Kagan, D.; Mackay, N.; Evans, Jonathan (2004-08-31)Potential anomalies are analysed for the local spin-3 and spin-4 classically conserved currents in any two-dimensional sigma model on a compact symmetric space G/H, with G and H classical groups. Quantum local conserved ...
