Abstract

We estimate gravitational waves produced during the formation of Q-balls associated with the Affleck-Dine mechanism in the gravity mediation on 3D lattice simulations. As a preliminary result, we find that the peak amplitude at the Q-ball formation epoch comes up to ΩGW ∼ 10 -3in/ Mpl)4 at the scale of physical size of Q-balls, k≈ 0.06m.
