A Review on ϕ Meson Production in Heavy-Ion Collision

Figure 4

(a) The ratio of the yields of , , , and normalised to nucleus-nucleus collisions and to corresponding yields in proton-proton collisions as a function of at 62.4 and 200 GeV [24]. Error bars are quadrature sum of statistical and systematic uncertainties. (b) The ratio of normalised yield of , , , , and in Pb + Pb collisions to the corresponding yield in ( + Be) collisions at 17.3 GeV (NA57 & NA49) [25, 26] and 2.76 TeV (ALICE) [21]. Only statistical uncertainties are shown.
