Abstract

In this work we consider the SU(N)SU(N) gauge theory with two Dirac fermions in the adjoint representation, in the limit of large NN. In this limit the infinite-volume physics of this model can be studied by means of the corresponding twisted reduced model defined on a single site lattice. Making use of this strategy we study the reduced model for various values of NN up to 289. By analyzing the eigenvalue distribution of the adjoint Dirac operator we test the conformality of the theory and extract the corresponding mass anomalous dimension.
