Chiral supergravitons interacting with a 0-brane N-extended NSR super-Virasoro group ☆

Abstract We continue the development of S AFF by examining the cases where there are N fermionic degrees of freedom associated with a 0-brane. These actions correspond to the interaction of the N -extended super-Virasoro algebra with the supergraviton and the associated SO( N ) gauge field that accompanies the supermultiplet. The superfield formalism is used throughout so that supersymmetry is explicit.
