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.proceeding for the Quark Matter Conference 2008 at Jaipur IndiaNuclear Experimenttext
