Abstract
We construct the finite energy path between topologically distinct vacua of a 4 dimensional SO(4) Higgs model which is known to support an instanton, and show that there is a sphaleron with Chern-Simons number N-CS = 1/2 at t he top of the energy barrier. This is carried out using the original geomet ric loop construction of Manton. (C) 1999 Elsevier Science B.V. All rights reserved.
