F-Term Inflation Q-Balls
arXiv:hep-th/0509141 · doi:10.1103/PhysRevD.73.043501
Abstract
A general analysis of Q-ball solutions of the supersymmetric F-term hybrid inflation field equations is given. The solutions consist of a complex inflaton field and a real symmetry breaking field, with a conserved global charge associated with the inflaton. It is shown that the Q-ball solutions for any value of the superpotential coupling, κ, may be obtained from those with κ= 1 by rescaling the space coordinates. The complete range of Q-ball solutions for the case κ= 1 is given, from which all possible F-term inflation Q-balls can be obtained. The possible role of F-term inflation Q-balls in cosmology is discussed.
