Query: Manifestly N=2 supersymmetric regularization for N=2 supersymmetric
  field theories   We formulate the higher covariant derivative regularization for N=2
supersymmetric gauge theories in N=2 harmonic superspace. This regularization
is constructed by adding the N=2 supersymmetric higher derivative term to the
classical action and inserting the N=2 supersymmetric Pauli--Villars
determinants into the generating functional for removing one-loop divergencies.
Unlike all other regularization schemes in N=2 supersymmetric quantum field
theory, this regularization preserves by construction the manifest N=2
supersymmetry at all steps of calculating loop corrections to the effective
action. Together with N=2 supersymmetric background field method this
regularization allows to calculate quantum corrections without breaking the
manifest gauge symmetry and N=2 supersymmetry. Thus, we justify the assumption
about existence of a regularization preserving N=2 supersymmetry, which is a
key element of the N=2 non-renormalization theorem. As a result, we give the
prove of the N=2 non-renormalization theorem which does not require any
additional assumptions.
