We here propose a 5-dimensional {\bf Abelian gauge} model based on the mixingbetween a $U(1)$ potential and an Abelian 3-form field by means of atopological mass term. An extended covariant derivative is introduced tominimally couple a Dirac field to the $U(1)$ potential, while this samecovariant derivative non-minimally couples the 3-form field to the chargedfermion. A number of properties are discussed in 5D; in particular, theappearance of a topological fermionic current. A 4-dimensional reduced versionof the model is investigated and, { \bf in addition to the $U(1)$ electric- andmagnetic-sort of fields,} there emerges an extra set of electric- andmagnetic-like fields which contribute a negative pressure and may be identifiedas a possible fraction of dark energy. The role of the topological fermioniccurrent is also contemplated upon dimensional reduction from 5D to 4D. Otherissues we present in 4 space-time dimensions are the emergence {\bf of apseudo-scalar massive particle,} an extra massive neutral gauge boson,{\bfwhich we interpret as a kind of paraphoton}, and the calculation of spin- andvelocity-dependent interparticle potentials associated to the exchange of theintermediate bosonic fields of the model.
