All (4,1): Sigma Models with (4,p) Off-Shell Supersymmetry

Författare: Chris Hull and Ulf Lindström,   Preprintnummer: UUITP-14/16 Off-shell (4, p) supermultiplets in 2-dimensions are constructed for p = 0, 1, 2, 4. These are used to construct sigma models whose target spaces are hyperka ̈hler with torsion. The off- shell supersymmetry implies the three complex structures are simultaneously integrable and allows us to construct actions using extended extended superspace and projective superspace, giving an explicit construction of the target space geometries.
