Unconstrained N=2 matter, Yang-Mills and supergravity theories in harmonic superspace
TL;DR: In this article, a new approach to N = 2 supersymmetry based on the concept of harmonic superspace is proposed and is used to give an unconstrained superfield geometric description of N=2 super Yang-Mills and supergravity theories as well as of matter N =2 hypermultiplets.

New N = 2 superconformal field theories in four dimensions
TL;DR: In this paper, the scaling dimensions of SU(2) N = 2 supersymmetric conformal field theories are analyzed in terms of the structure of relevant deformations of a y2 = x3 singular curve.

Anomaly-free chiral theories in six dimensions
TL;DR: In this paper, the authors considered the compactification of four dimensions on the manifold K 3 without requiring that the equations of motion be satisfied, leading to a large number of anomaly-free chiral supersymmetric six-dimensional theories.

Conserved currents and the energy-momentum tensor in conformally invariant theories for general dimensions
Johanna Erdmenger,Hugh Osborn +1 more
TL;DR: In this article, the implications of conformal invariance, as relevant in quantum field theories at a renormalization group fixed point, are analysed with particular reference to results for correlation functions involving conserved currents and the energy-momentum tensor.

Zero Value for the Three-Loop β Function in N = 4 Supersymmetric Yang-Mills Theory
TL;DR: In this paper, it was shown that the supersymmetric Yang-Mills theory is likely to be finite and conformally invariant order by order in perturbation theory.
