Integral formulae for the correlation functions of the XYZ model with a
boundary are calculated by mapping the model to the bosonized boundary SOS
model. The boundary K-matrix considered here coincides with the known general
solution of the boundary Yang-Baxter equation. For the case of diagonal
K-matrix, our formulae reproduce the one-point function previously obtained by
solving boundary version of quantum Knizhnik-Zamolodchikov equation.Comment: 35 pages, 12 figure
