Weak Skyrmions and sphalerons

  • Published:
Zeitschrift für Physik C Particles and Fields

Abstract

Recently proposed Skyrmion-like ansätze solve the field equations of the gauged non-linear sigma model. However, they are not classical solutions of the Weinberg-Salam model with finite Higgs coupling constant λ, where the only spherically symmetric solution is the hedgehog sphaleron.
