Electroweak Magnetism

摘要

The vacuum of the electroweak theory becomes unstable when a homogeneous magnetic field exceeds m/sub w//sup 2//e. Using Bogomol'nyi's method (requiring that the Higgs mass equals the Z mass) we find a static magnetic solution of the classical electroweak equations which is valid above m/sub w//sup 2//e. This solution corresponds to a vacuum condensate of W and Z bosons. The condensate anti-screens the magnetic field by means of the charged W-current. (ERA citation 14:005450)
