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

doi:10.1088/1674-1056/19/7/072501

Abstract 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 ¹⁶O—AgBr collisions at 60 A GeV, but not in ⁵⁶Fe—AgBr collisions at 500 A MeV, ⁸⁴Kr—AgBr collisions at 1.7 A GeV, ¹⁶O—AgBr collisions at 3.7 A GeV and ¹⁹⁷Au—AgBr collisions at 10.7 A GeV.

Keywords: relativistic heavy-ion collisions target fragmentation non-statistical fluctuation
