Studying the mechanisms of the hadron jets production in U+U collisions at $\sqrt{{}^{s}NN}=192$ GeV

Studying the properties and evolution of the quark-gluon plasma (QGP) is one of the main directions in modern nuclear physics. The leading direction in the QGP studies is the research of the particle production originating from hard scattering of partons produced in the ultra-relativistic heavy nuclei collision. Light mesons (π⁰, η and K_S) invariant spectra and nuclear modification factors measurements at high transverse momenta are used for the parton energy loss models free parameters estimate in large systems and to examine various scaling behaviours. Spherically asymmetric uranium nuclei at $\sqrt{{}^{s}NN}=192$ GeV are used to determine the influence of geometrical parameters of the colliding system on the fragmentation of hard partons produced in high energy collision of heavy nuclei. This paper presents differential transverse momentum spectra and nuclear modification factors of K_S mesons in U+U collisions at $\sqrt{{}^{s}NN}=192$ GeV measured in a wide transverse momentum range and different centrality intervals with PHENIX experiment at RHIC.
