| contents | This paper presents preliminary results from the NA61/SHINE experiment on $ϕ$ meson production in central Ar+Sc collisions at beam momenta of 150$A$, 75$A$, and 40$A$ GeV/$c$ (corresponding to $\sqrt{s_{NN}}$ = 16.8, 11.9, and 8.8 GeV, respectively). These results include double differential distributions in rapidity ($y$) and transverse momentum ($p_T$), as well as $p_T$-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 \pp reactions. Notably, this work represents the first-ever measurements of $ϕ$ production in a mid-sized system at SPS energies. |
