The Fate of Cosmic String Zero Modes
نویسنده
چکیده
Cosmic strings in realistic particle physics models have fermion zero modes in the string core. Such zero modes change the underlying cosmology; for example, the string can carry a current. We consider the stability of fermion zero modes to interactions with particles in the surrounding plasma. We also consider cosmological constraints on such theories, particulary those with a chiral fermion zero mode, such as arises in a class of supersymmetric models.

Destruction of Fermion Zero Modes on Cosmic Strings
We examine the existence of zero energy fermion solutions (zero modes) on cosmic strings in an SO(10) grand unified theory. The current carrying capability of a cosmic string formed at one phase transition can be modified at subsequent phase transitions. We show that the zero modes may be destroyed and the conductivity of the string altered. We discuss the cosmological implications of this, and...
متن کاملFermionic Zero Modes of Supergravity Cosmic Strings
Recent developments in string theory suggest that cosmic strings could be formed at the end of brane inflation. Supergravity provides a realistic model to study the properties of strings arising in brane inflation. Whilst the properties of cosmic strings in flat space-time have been extensively studied there are significant complications in the presence of gravity. We study the effects of gravi...

متن کاملZero modes on cosmic string loops
We study the spectrum of fermionic modes on cosmic string loops. We find no fermionic zero modes nor massive bound states — this implies that vortons stabilized by fermionic currents do not exist. We have also studied kink-(anti)kink and vortex-(anti)vortex systems and find that all systems that have vanishing net topological charge do not support fermionic bound modes.

Grand unified theories can admit cosmic strings with fermion zero modes. Such zero modes result in the string being current-carrying and the formation of stable remnants, vortons. However, the string zero modes do not automatically survive subsequent phase transitions. In this case the vortons dissipate. It is possible that the dissipating cosmic vortons create the observed baryon asymmetry of ...
