Three dimensional half-bosons and topological mass

A new mechanism is proposed for the phenomenon of topological mass generation in three spacetime dimensions as the result of the soldering of two massless half-boson modes of opposite signatures. This new interpretation, that extends similar phenomenon producing the massive vectorial mode of the 2D Schwinger model, is here exploited in the generation of the gauge invariant massive mode of the Maxwell-Chern-Simons theory. In the process, a new half-boson action is proposed for odd dimensional space-times to be used as the basic building blocks in the interference scheme. This action is the analog of the two-dimensional Floreanini-Jackiw action to higher dimensional spaces.
