We compute the glueball spectrum in (2+1)-dimensional Yang-Mills theory byanalyzing correlators of the Leigh-Minic-Yelnikov ground-state wave-functionalin the Abelian limit. The contribution of the WZW measure is treated by acontrolled approximation and the resulting spectrum is shown to reduce to thatobtained by Leigh et al., at large momentum.Comment: 9 page
