摘要：

We conjecture that the O(N)-symmetric non-linear sigma model (with N greater-than-or-equal-to 3) in the semi-infinite (1 + 1)-dimensional space is ''integrable'' with respect to the ''free'' and the ''fixed'' boundary conditions. We then derive, for both cases, the boundary S-matrix for the reflection of massive particles of this model off the boundary at x = 0.
