Abstract
Hadronic resonances play an important role in the study of the physics of heavy-ion collisions. In these proceedings, we discuss how the resonances can probe the reaction dynamics, the strangeness production and the properties of the hadronic phase in heavy-ion collisions at center-of-mass energies of sNN = 4–11 GeV. The resonance properties predicted by the general-purpose event generators are found to be very sensitive to the properties and space-time evolution of the medium produced in heavy-ion collisions.
Highlights
The resonances, which differ by mass and quark content, provide insights into the mechanisms that drive the multiplicity-dependent enhancement of strangeness production and can be used to study Parton energy loss and anomalous baryon-to-meson ratios at intermediate transverse momentum. Due to their short lifetimes, the hadronic resonances are sensitive to the rescattering and regeneration processes occurring between the chemical and the kinetic freeze-out in heavy-ion collisions
At NICA energies, the event generators predict the for particles with open strangeness
UrQMD [11], PHSD [12], AMPT [13] and EPOS [14] general-purpose event generators are sensitive to the properties of the medium produced at different stages of the heavy-ion collisions at NICA energies
Summary
At higher momenta, where identification of hadrons with different techniques becomes problematic, the particle multiplicities and the combinatorial background become reasonably low to allow for the extraction of the resonance peaks in the accumulated invariant mass distributions All these make measurements of resonances experimentally possible in a wide range of transverse momentum (pT ) even in the high multiplicity environment realized in central heavy-ion collisions. The resonances, which differ by mass and quark content, provide insights into the mechanisms that drive the multiplicity-dependent enhancement of strangeness production and can be used to study Parton energy loss and anomalous baryon-to-meson ratios at intermediate transverse momentum Due to their short lifetimes, the hadronic resonances are sensitive to the rescattering and regeneration processes occurring between the chemical and the kinetic freeze-out in heavy-ion collisions. We effectively expand the previous experience of the resonance studies and the inferred physics messages to the case of lower collision energies expected at the NICA collider, which is under construction at JINR in Dubna, Russia [9]
