A 1+1 field theory spectrum from M theory
arXiv:hep-th/0508058
Abstract
The spectrum of a 1+1 dimensional field theory with dynamical quarks is constructed. We focus in testing the possible brane embeddings that can support fundamental matter. The requirement on the wave function normalisation and the dependence on the quark mass of the quark condensate allow to discard most of the embeddings. We pay attention to some more general considerations comparing the behaviour of the non-compact theory at different dimensions. In particular we explored the possibility that the AdS/CFT duality ``formalism'' introduce a scale breaking parameter at (1+1)d allowing the existence of classical glueballs and its possible relation with point-like string configurations. The screening effects and the appearance of a possible phase transition is also discussed.
