Abstract
A search for the supersymmetric partner of the goldstino, the sgoldstino S, at LEP2 is presented. The production Sγ followed by S decay into two gluons or into two photons was studied at 189-202 GeV LEP centre-of-mass energies. No evidence for the S production was found and limits on the S mass corresponding to different theory parameters are given. (C) 2000 Elsevier Science B.V.
