System size and energy dependence of φ meson production at RHIC
Abstract
We present a system size and energy dependence of φ meson production in Cu+Cu and Au+Au collisions at sNN=62.4 GeV and 200 GeV measured by the STAR experiment at RHIC. We find that the number of participant scaled φ meson yields in heavy ion collisions over that of p+p collisions are larger than 1 and increase with collision energy. We compare the results with those of open-strange particles and discuss the physics implication.
