title = "Hyper-K{\"a}hler sigma models on (co)tangent bundles with SO ( n ) isometry",
abstract = "We construct N = 2 supersymmetric nonlinear sigma models whose target spaces are tangent as well as cotangent bundles over the quadric surface Qn - 2 = SO ( n ) / [ SO ( n - 2 ) × U ( 1 ) ]. We use the projective superspace framework, which is an off-shell formalism of N = 2 supersymmetry.",
