Abstract
We conjecture that the -symmetric non-linear sigma model in the semi-infinite -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 .
