Popis: Quark gluon plasma (QGP) is a state of quasi-free quarks and gluons matter, coming with temperatures larger then ~155 MeV. In laboratory, QGP is systematically observed in ultra-relativistic heavy nuclei collisions at RHIC and LHC. The jet-quenching effect is the one of QGP evidences, which manifests itself in hadron yields suppression at high transverse momenta region when compared with ones in proton-proton collisions. Asymmetric system of copper and gold nuclei collisions (Cu + Au) at 200 GeV is interesting for jet-quenching systematic studies as soon as it has a special nuclei overlap geometry different to one of symmetric systems (Au + Au or Cu + Cu). This paper presents KS-meson production results in Cu+Au collisions at 200 GeV.
