In this paper, we study an integrable system with both quadratic and cubic nonlinearity: m t = bu x + 1 2 k 1 m (u 2 −u 2 x ) x + 1 2 k 2 (2 mu x + m x u ) , m = u −u xx , where b, k 1 and k 2 are ar- bitrary constants. This model is kind of a cubic generalization of the Camassa–Holm (CH) equation: m t + m x u + 2 mu x = 0 . The equation is shown integrable with its Lax pair, bi- Hamiltonian structure, and infinitely many conservation laws. In the case b = 0 , peaked soliton (peakon), complex peakon, and multi-peakon solutions are studied. In particular, the two-peakon dynamical system is explicitly presented and their collisions are inves- tigated in details. In the case b = 0, the weak kink and kink-peakon interactional solu- tions are found for the first time. Significant difference from the CH equation is analyzed through a comparison. In the paper, we also investigate all possible smooth one-soliton solutions for the system.
