Broadhead, Matt and McDonald, John (2004) Two-field Q-ball solutions of supersymmetric hybrid inflation. Physical Review D, 69 (6). 063510. ISSN 1550-7998
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.
