Non-Abelian Tensor Towers and (2,0) Superconformal Theories

Understand

With the aim to study six-dimensional (2,0) superconformal theories with non-Abelian tensor multiplets we propose a five-dimensional superconformal action with eight supersymmetries for an infinite tower of non-Abelian vector, tensor and hypermultiplets.

• It describes the dynamics of the complete spectrum of the (2,0) theories compactified on a circle coupled to an additional vector multiplet containing the circle radius and the Kaluza-Klein vector arising from the six-dimensional metric.
• All couplings are only given in terms of group theoretical constants and the Kaluza-Klein levels.
• After superconformal symmetry is reduced to Poincare supersymmetry we find a Kaluza-Klein inspired action coupling super-Yang-Mills theory to an infinite tower of massive non-Abelian tensors.
