AB In this paper the kink scattering in a two-component scalar field theory model in (1+1)-Minkowskianspace-time is addressed. The potential term U(fi_1; fi_2) is given by a polynomial of fourth degree in thefirst field component and of sixth degree in the second one. The novel characteristic of this model isthat the kink variety describes two different types of extended particles. These particles are characterizedby its topological charge but also by a new feature determined by a discrete charge L = 0,1,-1.For this reason, the kink scattering involves a very rich variety of processes, which comprises kinkannihilation, reflection, charge exchange, transmutation, etc. It has been found that not only the finalvelocity of the scattered kinks, but also the final nature of the emerging lumps after the collision arevery sensitive on the initial velocities. Asymmetric scattering processes arise when Type I and TypeII particles are obliged to collide. In this case, ten different final scenarios are possible. Symmetricscattering events are also discussed.
