Topological Bϕ Model

A topological model (in the sense that it is metric independent) defined in three-dimensional spacetime which involves a 2-form and a 0-form fields, namely [1]. The bosonic model can be obtained after dimensional reduction of the four-dimensional BF model [2] and appropriate choice of terms. An N = 1 supersymmetric version of this model can be constructed in the three-dimensional superspace

where B ^α is a spinorial superfield which contains a 2-form (Kalb-Ramond) field and Φ is a real scalar superfield [3]. This term can be useful in order to construct a mass generation mechanism for the Kalb-Ramond field .
