Abstract

The energy and system size dependence of pseudorapidity (η) and multiplicity distributions of photons are measured in the region −2.3 ≤ η ≤ −3.7 for Cu + Cu collisions at and 62.4 GeV. Photon multiplicity measurements at forward rapidity have been carried out using a Photon Multiplicity Detector (PMD) in the STAR experiment. Photons are found to follow longitudinal scaling for Cu + Cu collisions for 0–10% centrality. A Comparison of pseudorapidity distributions with HIIJING model is also presented.
