Supercharges in the hyper-Kähler with torsion supersymmetric sigma models
Résumé
We construct explicitly classical and quantum supercharges satisfying the standard N=4supersymmetryalgebra in the supersymmetric sigma models describing the motion over hyper-Kähler with torsion manifolds. One member of the family of superalgebras thus obtained is equivalent to the superalgebra derived and formulated earlier in purely mathematical framework.
