Cu+Cu 22.4 GeV Charged Hadron Spectra

Identified charged particle spectra of π±, K±, p and p measured using energy loss in the STAR TPC are reported for (|y|<0.1) for Cu+Cu collisions at √(SNN ) = 22.4 GeV. Total particle production, particle ratios, and average transverse momenta, are presented for different collision centralities. Kinetic and chemical freezeout properties are presented as a function of the number of participating nucleons for the system. These results are compared with previously published results from collisions of different systems (Pb+Pb or Au+Au) at similar collision energies.

[Note: Analysis ongoing]

The Cu+Cu 22 GeV Dataset was taken during run 5 and was the second running at the AGS injection energy (AuAu 19.6 GeV in run 2 was the first). It was taken from Mar-22 through the 24th.
