Two-Field Q-ball Solutions of Supersymmetric Hybrid Inflation
arXiv:hep-ph/0309298 · doi:10.1103/PhysRevD.69.063510
Abstract
We demonstrate the existence of two-field Q-ball solutions of the scalar field equations of supersymmetric D- and F-term hybrid inflation. The solutions consist of a complex inflaton field together with a real symmetry breaking field. Such inflatonic Q-balls may play a fundamental role in reheating and the post-inflation era of supersymmetric hybrid inflation models.
