摘要
We study the beam-energy and system-size dependence of ϕ meson production (using the hadronic decay mode ϕ→K+K−) by comparing the new results from Cu+Cu collisions and previously reported Au+Au collisions at sNN=62.4 and 200 GeV measured in the STAR experiment at RHIC. Data presented in this Letter are from mid-rapidity (|y|<0.5) for 0.4更多
