Abstract

Nodal, excited compactons in the CPN\mathbb{C}P^N models with V-shaped potentials are analyzed. It is shown that the solutions exist as compact QQ-balls and QQ-shells. The solutions have a discontinuity in the second derivative associated with the character of the potential, however, their energy and charge densities are both continuous. The excited QQ-balls and QQ-shells are analyzed as electrically neutral and electrically charged objects.
