Flux-Tube Ring and Glueball Properties in the Dual Ginzburg-Landau Theory
Abstract
An intuitive approach to the glueball using the flux-tube ring solution in the dual Ginzburg-Landau theory is presented. The description of the flux-tube ring as the relativistic closed string with the effective string tension enables us to write the hamiltonian of the flux-tube ring using the Nambu-Goto action. Analyzing the Schr\"odinger equation, we discuss the mass spectrum and the wave function of the glueball. The lowest glueball state is found to have the mass MG 1.6 GeV and the size RG 0.5 fm.
