K⁎(892) and ϕ(1020) production and their decay into the hadronic medium at the Large Hadron Collider

The production of the K⁎(892) strange resonance in Pb+Pb collisions at sNN=2.76 TeV LHC energy is analyzed within the integrated hydrokinetic model (iHKM) at different equations of state of superdense matter. The similar analysis is done also for the RHIC top energy sNN=200 GeV for comparison purposes. A modification of experimental K⁎(892)-identification is studied for different centralities in view of possible re-scattering of the decay products at the afterburner stage of the fireball evolution. We see quite intensive rescattering of the decay products as well as recombination processes for K⁎(892). In addition, the production of the much longer-long-lived ϕ(1020) resonance with hidden strange quark content is investigated.
