摘要
We solve numerically for periodic, spherically symmetric, classical solutions of SU(2)-Higgs theory in four-dimensional Euclidean space. In the limit of short periods the solutions approach tiny instanton-antiinstanton superpositions while, for longer periods, the solutions merge with the static sphaleron. A previously predicted bifurcation point. where two branches of periodic solutions meet, appears for Higgs boson masses larger than 3.091M(W). [S0556-2821(99)02520-5].
