Energy dependence of ϕ(1020) meson production in nucleus-nucleus collisions at the CERN SPS
This paper presents preliminary results from the NA61/SHINE experiment on ϕ meson production in central Ar+Sc collisions at beam momenta of 150A, 75A, and 40A GeV/c (corresponding to √sNN, and 8.8 GeV, respectively). These results include double differential distributions in rapidity (y) and transve...

| description | This paper presents preliminary results from the NA61/SHINE experiment on ϕ meson production in central Ar+Sc collisions at beam momenta of 150A, 75A, and 40A GeV/c (corresponding to √sNN, and 8.8 GeV, respectively). These results include double differential distributions in rapidity (y) and transverse momentum (pT), as well as pT -integrated rapidity distributions and total ϕ yields. Additionally, the widths of the rapidity distributions of ϕ and ϕ/π yield ratios are compared to those from Pb+Pb and p+p reactions. Notably, this work represents the first-ever measurements of ϕ production in a mid-sized system at SPS energies. |
