Solitosynthesis of Q-balls | | Marieke Postma
; | | Date: |
15 Oct 2001 | | Journal: | Phys.Rev. D65 (2002) 085035 | | Subject: | hep-ph | | Abstract: | We study the formation of Q-balls in the early universe, concentrating on potentials with a cubic or quartic attractive interaction. Large Q-balls can form via solitosynthesis, a process of gradual charge accretion, provided some primordial charge assymetry and initial ``seed’’ Q-balls exist. We find that such seeds are possible in theories in which the attractive interaction is of the form $A H psi^* psi$, with a light ``Higgs’’ mass. Condensate formation and fragmentation is only possible for masses $m_psi$ in the sub-eV range; these Q-balls may survive untill present. | | Source: | arXiv, hep-ph/0110199 | | Services: | Forum | Review | PDF | Favorites | |
