Boundary S-matrix of the $O(N)$-symmetric Non-linear Sigma Model

High Energy Physics - Theory 2009-10-28 v1

Abstract

We conjecture that the O(N)O(N)-symmetric non-linear sigma model in the semi-infinite (1+1)(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=0x=0.
