Extended Variational Approach to the SU(2) Mass Gap on the Lattice
arXiv:hep-ph/9405311 · doi:10.1103/PhysRevD.51.1298
Abstract
The linear delta expansion is applied to a calculation of the SU(2) mass gap on the lattice. Our results compare favourably with the strong-coupling expansion and are in good agreement with recent Monte Carlo estimates.
