Q-ball perturbations with more details: linear analysis vs lattice
Aleksandr Azatov, Quoc Trung Ho, Mohamed Mahdi Khalil
We analyze in detail the interactions between non-topological soliton (Q-ball) and its perturbations. We extend the previous literature by carefully identifying the domain of appli…
