\(N=1\) supersymmetric sigma model with boundaries. II. (English) Zbl 1097.81548
Summary: We consider the \(N=1\) supersymmetric two-dimensional nonlinear sigma model with boundaries and nonzero B-field. By analysing the appropriate currents we describe the full set of boundary conditions compatible with \(N=1\) superconformal symmetry. Using this result the problem of finding a correct action is discussed. We interpret the supersymmetric boundary conditions as a maximal integral submanifold of the target space manifold, and speculate about a new geometrical structure, the deformation of an almost product structure.
