Two-dimensional multiplicity fluctuation analysis of target residues in nuclear collisions

Multiplicity fluctuation of the target residues emitted in the interactions in a wide range of projectile energies from 500 A MeV to 60 A GeV is investigated in the framework of two-dimensional scaled factorial moment methodology. The evidence of non-statistical multiplicity fluctuation is found in (16)O-AgBr collisions at 60 A GeV, but not in (56)Fe-AgBr collisions at 500 A MeV, (84)Kr-AgBr collisions at 1.7 A GeV, (16)O-AgBr collisions at 3.7 A GeV and (197)Au-AgBr collisions at 10.7 A GeV.
