Rm. Doria et al., THE MINIMAL COUPLING OF CHARGED SPIN-3 2 FIELDS TO AN EXTENDED ABELIAN GAUGE-MODEL/, Communications in Theoretical Physics, 21(1), 1994, pp. 121-124
Charged spin-3/2 fields are coupled to an extended gauge model without
the total suppression of the vector degrees of freedom which usually
takes place as a consequence of simultaneously imposing the Maxwell an
d Rarita-Schwinger U(1) symmetries.
