Boundary Bound States in Affine Toda Field Theory

Fring, A. & Köberle, R. (1995). Boundary Bound States in Affine Toda Field Theory. International Journal of Modern Physics A (ijmpa), 10(05), pp. 739-751. doi: 10.1142/s0217751x95000346


We demonstrate that the generalization of the Coleman-Thun mechanism may be applied to the situation, when considering scattering processes in 1+1-dimensions in the presence of reflecting boundaries. For affine Toda field theories we find that the binding energies of the bound states are always half the sum over a set of masses having the same colour with respect to the bicolouration of the Dynkin diagram. For the case of $E_6$-affine Toda field theory we compute explicitly the spectrum of all higher boundary bound states. The complete set of states constitutes a closed bootstrap.
