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

Abstract:

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.
