[en] 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 $\sqrt{s_{NN}}$= 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. (paper)

[en] The PHENIX experiment at the relativistic heavy ion collider (RHIC) finished data taking in 2016. However, large datasets collected in different collision systems (p+p, p+A and A+A) at different energies (√s_NN = 19-500 GeV) during the last years of the detector operation are actively analysed by the collaboration and bring a wealth of new experimental results. This paper reviews the most recent PHENIX results on the light flavour hadron production, yields and angular correlations of the direct photons in heavy-ion collisions as well as on the search for the onset of collectivity in high multiplicity p+p and p+A collisions.

[en] The main goal of the future NICA-MPD experiment is studying the dense baryonic matter produced in heavy-ion collisions in the energy range 4-11 GeV and searching for signs of the phase transition between hadronic matter and deconfined quark-gluon plasma. Measurements of soft thermal photon yields and collective flow can significantly extend the physics program of the MPD experiment, allowing one to probe the temperature and the level of thermalizaion of the medium created in heavy ion collisions at NICA energies. The optimal method to measure soft photons is to register photon conversions in the material of the tracking system. In this contribution, recent RHIC and LHC results on thermal photon spectra and flow will be presented. Motivation and feasibility of thermal photon measurements with the conversion method in the projected MPD setup will be discussed.

[en] Measurements of K^*(892) meson production provide the means to study properties of relativistic heavy-ion collisions. Because of their short lifetimes, the charged and neutral K^*(892) mesons provide information about the properties of the late hadronic phase due to the presence of rescattering and regeneration effects that can modify resonance yields. The K^*(892) mesons can also be used to study the various mechanisms that shape particle transverse momentum (pT) spectra, including the collective flow, in-medium parton energy loss and recombination. Measurement of neutral K^*(892) mesons requires reconstruction of the charged pions and kaons originating from the primary vertex. At the same time, the measurement of charged K^*(892) mesons involves reconstruction of the weakly decaying Ks mesons. Simultaneous measurement of the two particles is a way to minimize systematic uncertainties of the corresponding physical studies. We present results of feasibility studies for measurement of the charged and neutral K^*(892) mesons in the MPD experimental setup in heavy-ion collisions at NICA energies. Results are obtained using full-scale Monte Carlo simulations of the experimental setup.
