K^*(892) and φ(1020) production and their decay into the hadronic medium at the Large Hadron Collider
read the original abstract
The production of the $K^*(892)$ strange resonance in Pb+Pb collisions at $\sqrt{s_{NN}}=2.76$ 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 $\sqrt{s_{NN}}=200$ 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 $\phi(1020)$ resonance with hidden strange quark content is investigated.

Probing Late-Stage Hadronic Interactions at High Baryon Density via $K^{*0}$ Production in the RHIC Beam Energy Scan Program
K*0/K yield ratios in central Au+Au collisions at BES energies are suppressed relative to peripheral collisions and thermal predictions, indicating hadronic rescattering that strengthens at lower energies.
