Wess-Zumino and super Yang-Mills theories in D=4 integral superspace

We reconstruct the action ofN= 1,D= 4 Wess-Zumino andN= 1,2,D= 4super-Yang-Mills theories, using integral top forms on thesupermanifoldM(4|4). Choosingdifferent Picture Changing Operators, we show the equivalence of their rheonomic andsuperspace actions. The corresponding supergeometry and integration theory are discussedin detail. This formalism is an efficient tool for building supersymmetric models in ageometrical framework
