Massless gauge superfields of higher integer superspins
Kuzenko S. M. , Sibiryakov A. G.
Two (dual) superfield formulations are proposed for free massless N= l, D=4 supermultiplets (s, .r+l/2), where s=l, 2,... . For s=l one of these versions is identical to the nonminimal formulation for the supermultiplet (l, 3/2) [E. S. Fradkin and M. Vasiliev, Nuovo Cim. Lett. 25, 79 (1979); B. de Witt and J. W. van Holten, Nucl. Phys. В 155, 530 (1979); S. J. Gates and W. Siegel, Nucl. Phys. В 164, 484 (1980)].
