Boundary Reflection Matrix for Affine Toda Field Theory
arXiv:hep-th/9505138 · doi:10.1103/PhysRevD.53.4441
Abstract
We present one loop boundary reflection matrix for Toda field theory defined on a half line with the Neumann boundary condition. This result demonstrates a nontrivial cancellation of non-meromorphic terms which are present when the model has a particle spectrum with more than one mass. Using this result, we determine uniquely the exact boundary reflection matrix which turns out to be \lq non-minimal' if we assume the strong-weak coupling \lq duality'.
