Periodic instantons in SU(2) Yang-Mills-Higgs theory

摘要

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. An interesting new class of bifurcating complx periodic instanton solutions to the Yang-Mills Higgs equations is described as well.
