Sažetak
The production of K+, K- and ϕ(1020) mesons is studied in Al+Al collisions at a beam energy of 1.9A GeV which is close to or below the production threshold in NN reactions. Inverse slopes, anisotropy parameters, and total emission yields of K ± mesons are obtained. A comparison of the ratio of kinetic energy distributions of K- and K+ mesons to the HSD transport model calculations suggests that the inclusion of the in-medium modifications of kaon properties is necessary to reproduce the ratio. The inverse slope and total yield of ϕ mesons are deduced. The contribution to K- production from ϕ meson decays is found to be [17±3(stat)+2-7(syst)]%. The results are in line with the previous K± and ϕ data obtained for different colliding systems at similar incident beam energies.
