Author(s) from Durham


The CP2 model, with and without a generalized Hopf term, is studied using the
collective coordinate approximation. In the spirit of this approximation, an ansatz is given for
the head-on collision of two solitons. The equations of motion for the collective coordinates
are then solved analytically, for solitons close together and for solitons far apart. The solutions
show how the generalized Hopf term changes the scattering angle, which in its absence, is 90◦.
