Abstract: Consistent interactions that can be added to a free, Abelian gauge theorycomprising a collection of BF models and a set of three-form gauge fields areconstructed from the deformation of the solution to the master equation basedon specific cohomological techniques. Under the hypotheses of smooth, local, PTinvariant, Lorentz covariant, and Poincare invariant interactions, supplementedwith the requirement on the preservation of the number of derivatives on eachfield with respect to the free theory, we obtain that the deformation proceduremodifies the Lagrangian action, the gauge transformations as well as theaccompanying algebra.
