Dissipating Cosmic Vortons and Baryogenesis
Anne-Christine Davis, Warren B. Perkins
Grand unified theories can admit cosmic strings with fermion zero modes which result in the string carrying a current and the formation of stable remnants, vortons. We consider the…
Generic Current-Carrying Strings
Anne-Christine Davis, Warren B. Perkins
We investigate the standard model in a cosmic string background and show that the electroweak symmetry is partially restored. For a range of parameters the electroweak Higgs field…
On the Evolution of Primordial Magnetic Fields
K. Dimopoulos, A. C. Davis
A new mechanism for the evolution of primordial magnetic fields is described and analysed. The field evolution is followed from the time of its creation until the epoch of structur…
Microphysics of SO(10) Cosmic Strings
Anne-Christine Davis, Stephen C. Davis
We uncover a rich microphysical structure for SO(10) cosmic strings. For the abelian string the electroweak symmetry is restored around it in a region depending on the electroweak…
The Impossibility of Baryogenesis at a Second Order Electroweak Phase Transition
Tomislav Prokopec, Robert Brandenberger, Anne-Christine Davis
We investigate whether baryogenesis is possible at a second order electroweak phase transition. We find that under rather general conditions, the departure from thermal equilibrium…
