  • We construct Q-ball solutions from a model consisting of one massive scalar field $ξ$ and one massive complex scalar field $ϕ$ interacting via the cubic couplings $g_1 ξϕ^{*} ϕ+ g_2 ξ^3$, typical of Henon-Heiles-like potentials. Although being formally simple, these couplings allow for Q-balls. In one spatial dimension, analytical solutions exist, either with vanishing or non vanishing $ϕ$. In three spatial dimensions, we numerically build Q-ball solutions and investigate their behaviours when changing the relatives values of $g_1$ and $g_2$. For $g_1<g_2$, two Q-balls with the same frequency exist, while $ω=0$ can be reached when $g_1>g_2$. We then extend the former solutions by gauging the U(1)-symmetry of $ϕ$ and show that charged Q-balls exist.
