Production and reconstruction of short-lived resonances in heavy-ion collisions at NICA energies using the MPD detector

Abstract

The short-lived resonances have been used to study properties of the heavy-ion collisions at SPS, RHIC and the LHC. The resonance yields measured in the hadronic decay channels are affected by the rescattering and regeneration effects in the late hadronic phase. The mesonic and baryonic resonances with different strangeness content are used to study the strangeness enhancement phenomenon predicted as one of the signatures for the QCD phase transition. Having different masses and baryonic numbers, the resonances contribute to the study of hadronization mechanisms at low and intermediate transverse momenta. The extensive resonance measurements are not experimentally available in heavy-ion collisions at NICA energies. In this contribution, we study the resonance properties and their sensitivity to different stages of Au+Au collisions at = 4–11 GeV. Results of feasibility studies for reconstruction of ρ(770)0, K*(892), ϕ(1020), Λ(1520), Σ(1385)± and Ξ(1530)0 resonances in the MPD detector at NICA are presented and discussed.
