摘要：

We present a complete study of boundary bound states and related boundary S-matrices for the sine-Cordon model with Dirichlet boundary conditions. Our approach is based partly on the bootstrap procedure and partly on the explicit solution of the inhomogeneous XXZ model with boundary magnetic field and solution of the boundary Thirring model. We identify boundary bound states with new 'boundary strings' in the Bethe ansatz. The boundary energy is also computed.
