Study of large-NYang-Mills theory in2+1dimensions

The bound state problem in (2+1)-dimensional large-N Yang-Mills theory is accurately solved using the light-front Hamiltonian of transverse lattice gauge theory. We conduct a thorough investigation of the space of couplings on coarse lattices, finding a single renormalized trajectory on which Poincaré symmetries are enhanced in bound state solutions. Augmented by existing data from finite-N Euclidean lattice simulations, we obtain accurate estimates of the low-lying glueball spectrum at $N=\infty .$
