Abstract:
The question of the integrability of real-coupling affine toda field theory on a half line is discussed. It is shown, by examining low-spin conserved charges, that the boundary conditions preserving integrability are strongly constrained. In particular, among the cases treated so far, , and , there can be no free parameters introduced by such boundary conditions; indeed the only remaining freedom (apart from choosing the simple condition ), resides in a choice of signs. For a special case of the boundary condition, accessible only for , it is pointed out that the classical boundary bound state spectrum may be related to a set of reflection factors in the quantum field theory. Some preliminary calculations are reported for other boundary conditions, demonstrating that the classical scattering data satisfies the weak coupling limit of the reflection bootstrap equation.
