Precision study of large-N Yang-Mills theory in 2+1 dimensions
S. Dalley, B. van de Sande
Abstract
The boundstate 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 renormalised trajectory on which Poincaré symmetries are enhanced in boundstate solutions. Augmented by existing data from finite-N Euclidean lattice simulations, we obtain accurate estimates of the low-lying glueball spectrum at N=infinty
