Abstract

We investigate the monopole-antimonopole pair solution in the SU(2) x U(1) Weinberg-Salam theory with ϕ-winding number, n=3 for bifurcation phenomena. The magnetic monopole merges with antimonopole to form a vortex ring with finite diameter at n=3. Other than the fundamental solution, two new bifurcating solution branches were found when Higgs coupling constant λ, reaches a critical value λ_c. The two new branches possess higher energies than the fundamental solutions. These bifurcating solutions behave differently from the vortex ring configuration in SU(2) Yang-Mills-Higgs theory since thery are full vortex-ring. We investigate on the total energy E, vortex ring diameter d_ρ, and magnetic dipole moment μ_m, for 0 ≤ λ≤ 49.
