We consider topology-changing processes in the $SU(2)$ Higgs theory. In the standard model of particle physics, they are accompanied by baryon- and lepton-number violation. At a fixed energy and multiplicity of the initial state, these processes are described by classical $\theta$-instanton solutions. We find these solutions and calculate the suppression exponents for the probabilities of the topology-changing transitions at relatively low energies.
Keywords: electroweak model, fermion-number violation.
Mots-clés : instanton transitions
