Periodic Instantons in SU(2) Yang-Mills-Higgs Theory
arXiv:hep-ph/9905243 · doi:10.1016/S0370-2693(00)00022-8
Abstract
The properties of periodic instanton solutions of the classical SU(2) gauge theory with a Higgs doublet field are described analytically at low energies, and found numerically for all energies up to and beyond the sphaleron energy. Interesting new classes of bifurcating complex periodic instanton solutions to the Yang-Mills-Higgs equations are described.
