A Review on ϕ Meson Production in Heavy-Ion Collision

Figure 13

The integrated proton and meson for various centre-of-mass energies for 0–80% centrality in Au + Au collisions [32]. Vertical lines are the statistical error and systematic errors are shown by cap symbol. For lower RHIC energies, STAR preliminary spectra were used for and proton calculation [17, 33, 34]. The red and blue lines are the fit to the and proton by empirical function just to guide the eye of the reader.
