In this paper, fermions are minimally coupled to 3D-gravity where a dynamicaltorsion is introduced. A Kalb-Ramond field is non-minimally coupled to thesefermions in a gauge-invariant way. We show that a 1-loop mass generationmechanism takes place for both the 2-form gauge field and the torsion. As forthe fermions, no mass is dynamically generated: at 1-loop, there is only a massshift proportional to the Yukawa coupling whenever the fermions have anon-vanishing tree-level mass.Comment: 13 pages, latex file, no figures, some corrections adde
