Query: Chiral formulation for hyperkaehler sigma-models on cotangent bundles of
  symmetric spaces   Starting with the projective-superspace off-shell formulation for
four-dimensional N = 2 supersymmetric sigma-models on cotangent bundles of
arbitrary Hermitian symmetric spaces, their on-shell description in terms of N
= 1 chiral superfields is developed. In particular, we derive a universal
representation for the hyperkaehler potential in terms of the curvature of the
symmetric base space. Within the tangent-bundle formulation for such
sigma-models, completed recently in arXiv:0709.2633 and realized in terms of N
= 1 chiral and complex linear superfields, we give a new universal formula for
the superspace Lagrangian. A closed form expression is also derived for the
Kaehler potential of an arbitrary Hermitian symmetric space in Kaehler normal
coordinates.
