Stability of Two Doublet Electroweak Strings
Michael A. Earnshaw, Margaret James
Vortex solutions in the two Higgs doublet electroweak model are constructed, and their stability to small perturbations is studied. The most general perturbation is decomposed into…
The Origin of the Sphaleron Dipole Moment
Mark Hindmarsh, Margaret James
By providing a suitable definition of the electromagnetic field off the Higgs vacuum, we show that within the sphaleron there is a monopole-antimonopole pair with quantized charges…
Detailed Stability Analysis of Electroweak Strings
Margaret James, Leandros Perivolaropoulos, Tanmay Vachaspati
We give a detailed stability analysis of the Z-string in the standard electroweak model. We identify the mode that determines the stability of the string and numerically map the re…
On the Stability of Electroweak Strings (New Version)
M. James, L. Perivolaropoulos, T. Vachaspati
We map the parameter space that leads to stable Z-vortices in the electroweak model. For , we find that the strings are unstable for a Higgs mass larger than 24 G…
