From Q-walls to Q-balls | R. B. MacKenzie

10 Apr 2001 | Journal: | JHEP 0108 (2001) 003 | Subject: | hep-th | Abstract: | We study $Q$-ball type solitons in arbitrary spatial dimensions in the setting recently described by Kusenko, where the scalar field potential has a flat direction which rises much slower than $phi^2$. We find that the general formula for energy as a function of the charge is, $E_dsim Q_d^{(d/d+1)}$ in spatial dimension $d$. We show that the Hamiltonian governing the stability analysis of certain $Q$-wall configurations, which are one dimensional $Q$-ball solutions extended to planar, wall-like configurations in three dimensions, can be related to supersymmetric quantum mechanics. $Q$-wall and $Q$-string (the corresponding extensions of 2 dimensional $Q$-balls in 3 spatial dimensions) configurations are seen to be unstable, and will tend to bead and form planar or linear arrays of 3 dimensional $Q$-balls. The lifetime of these wall-like and string-like configurations is, however, arbitrarily large and hence they could be of relevance to cosmological density fluctuations and structure formation in the early Universe. | Source: | arXiv, hep-th/0104084 | Services: | Forum | Review | PDF | Favorites |
