Massless gauge superfields of higher half-integer superspins
Kuzenko S. M. , Postnikov V. V., Sibiryakov A. G.
Two superfield formulations (dual with respect to one another) are proposed for free massless N= l, D=A supersymmetric theories of superspin (s+l/2), where 5=2,3,.... For s=l the first version reduces to linearized η = — I nonminimal supergravity and the second version reduces to linearized minimal supergravity.
