چکیده

The standard model for the electroweak interactions is known 1,2,3,4 to contain vortex solutions that are the usual Nielsen-Olesen U(1) vortices 5 embedded in the larger electroweak symmetry group SU(2) × U(1). After briefly describing these vortex solutions, I will discuss their stability and argue that the presence of bound states can stabilize them. Then I will draw an intimate connection between the sphaleron 2 and electroweak strings and show how the sphaleron can be reinterpreted as a segment or a loop of electroweak string 6. In the notation of Ref. 7, the three linearly independent electroweak string solutions are the W 1 string, Φ = fNO(r)e iτθ (

We consider dyon configurations in the standard electroweak model. In the presence of a θ term and no fermions, the usual result q = (n+ θ/2π)e is obtained for the electric charge spectrum. The effect of including standard model fermions is discussed qualitatively.
