Polar supermultiplets , Hermitian symmetric spaces and hyperkähler metrics


We address the construction of four-dimensional N = 2 supersymmetric nonlinear sigma models on tangent bundles of arbitrary Hermitian symmetric spaces starting from projective superspace. Using a systematic way of solving the (infinite number of) auxiliary field equations along with the requirement of supersymmetry, we are able to derive a closed form for… (More)
