摘 要：The Electroweak Skyrmion (EWS) is a non-topological soliton of the electroweak sector of the Standard Model that arises when a stabilizing dimension-8 operator is included. We present a numerical solution of the equations of motion, which provides the mass, the radius and the magnetic moment of the classical EWS. We also discuss the quantization of the light degrees of freedom (spin, isospin and breather) and show that the EWS is a boson. From the classical solution, we infer the interaction potential between two well-separated EWSs and the fermionic number arising from the coupling between the soliton fields and the Standard Model leptons. We discuss the quantum stability of the EWS and roughly estimate its decay rate.
