要旨:
We determine the one-loop deformation of the conformal symmetry of a general N=2 superconformally invariant Yang-Mills theory. We compute the deformation for several explicit examples which have a realization as world-volume theories on a stack of D3 branes. This imposes restrictions on the effective action which we study on a subset of the Coulomb branch which corresponds to seperating one brane from the stack.
