Anomalous N=2 Superconformal Ward Identities
The N=2 superconformal Ward identities and their anomalies are discussed in N=2 superspace (including N=2 harmonic superspace), at the level of the low-energy effective action (LEEA) in four-dimensional N=2 supersymmetric field theories. The (first) chiral N=2 supergravity compensator is related to the known N=2 anomalous Ward identity in the N=2 (abelian) vector mulitplet sector. As regards th...
متن کاملSuperconformal Ward Identities and Their Solution
Superconformal Ward identities are derived for the the four point functions of chiral primary BPS operators for N = 2, 4 superconformal symmetry in four dimensions. Manipulations of arbitrary tensorial fields are simplified by introducing a null vector so that the four point functions depend on two internal R-symmetry invariants as well as two conformal invariants. The solutions of these identi...
متن کاملJuly Superconformal Ward Identities and N = 2 Yang-mills Theory
A reformulation of the superconformal Ward identities that combines all the supercon-formal currents and the associated parameters in one multiplet is given for theories with rigid N = 1 or N = 2 supersymmetry. This form of the Ward Identities is applied to spontaneously broken N = 2 Yang-Mills theory and used to derive a condition on the low energy effective action. This condition is satisfied...

متن کاملSuperconformal invariance from N = 2 supersymmetry Ward identities
We algebraically prove the cancellation of the β function at all order of perturbation theory of N = 2 supersymmetric gauge theories with a vanishing one-loop β function. The proof generalises that recently given for the N = 4 case. It uses the consistent Slavnov–Taylor identities of the shadow dependent formulation. We also demonstrate the cancellation at all orders of the anomalous dimensions...
