An irreducible massive superspin one half action built from the chiral dotted spinor superfield

An irreducible massive superspin one half action built from the chiral dotted spinor superfield

Although the chiral dotted spinor superfield should describe a Massive Superspin One Half multiplet, it has not been obvious how to derive this from an action. In this paper this is done by including a chiral undotted spinor superfield, finding the BRST transformations that govern both of these, and...
