Phys. Rev. D 63, 047301 (2001) [4 pages]New mechanism for the generation of primordial seeds for the cosmic magnetic fields
M. Gasperini Received 10 July 2000; published 31 January 2001 We discuss the inflationary production of magnetic seeds for the galactic dynamo through photon-graviphoton mixing, typical of extended models of local supersymmetry. An analysis of the allowed region in parameter space shows that such a mechanism is compatible with existing phenomelogical bounds on the vector mass and mixing parameter, but requires a large enough mixing that seems difficult to implement naturally in the context of a minimal supersymmetric scenario. ©2001 The American Physical Society
