Resum: |
We show that the Z strings of the standard electroweak theory can be stabilized by strong external magnetic fields, provided that β1/2≡MH/MZ≤1, where MH and MZ are the Higgs and Z masses. The magnetic fields needed are larger than β1/2Bc and smaller than Bc, where Bc≡M2W/e is the critical magnetic field which causes W condensation in the usual broken phase vacuum. If such magnetic fields were present after the electroweak transition, they would stabilize strings for a period comparable to the inverse Hubble rate at that time. Pair creation of monopoles and antimonopoles linked by segments of string is briefly considered. |
