abstract

We conjecture that the $O(N)$-symmetric non-linear sigma model 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 $x=0$.

Discussion (0). Continue with ORCID to comment.

String Integrability on the Coulomb Branch
hep-th 2025-06 conditional novelty 6.0 of 10

A dynamical, spectral-parameter-dependent reflection matrix is constructed for strings ending on the Coulomb-branch D3-brane, proving classical integrability of the boundary sigma-model.
