“…In high-energy heavy-ion collisions, the correlation femtoscopy technique may be utilized to assess the spatial and temporal extents of the particle-emitting region. The extracted from the analysis femtoscopic radii represent collective effects in a variety of ways most notably in their dependence on the transverse pair momentum [18][19][20][21][22]. One way for examining the particle production process is to measure the spatial and temporal scales of the particle-emitting source.…”

Brookhaven National Laboratory (BNL) is a multipurpose research center that primarily supported by the U.S. Department of Energy (DOE) Office of Science. BNL operates cutting-edge large-scale facilities for studies in physics, chemistry, biology, medicine, applied science, and a wide range of advanced technologies. Relativistic Heavy Ion Collider (RHIC) is a megascience facility at BNL that allows to conduct research in nuclear and particle physics. In these proceedings, we will review the current status and future prospects of the megascience complex RHIC.

“…The R long values estimated for kaons are generally larger than those for pions. This difference may come from the resonance decays [33], such as K * and φ mesons.…”

“…The identical kaon analyses are expected to provide a cleaner probe as compared to pions because they are less affected by resonance decays. Theoretical calculations [33] and experimental experimental measurements [34] at LHC energies demonstrated that kaon radii can be described only if the hadronic rescattering phase follows the hydrodynamic phase [35].…”

The results of the model analysis of hadron femtoscopic correlations and factorial moments of particle multiplicity in heavy ion collisions for the energy range of the Beam Energy Scan (BES) program at RHIC and future NICA collider are presented. For this purpose, the simulation of Au+Au collisions at center-of-mass energies 7.7 and 11.5 GeV per nucleon pair using the UrQMD, vHLLE+UrQMD (with the crossover and first-order equation of states), and HYDJET++ event generators was performed. The sensitivity of pion and kaon correlation radii and the dependence of the factorial moments on heavy ion beam energy to quark–hadron phase transition details was studied. In addition, the possible influence of some relevant detector effects on the corresponding experimental observables is discussed.

“…In our previous papers [57][58][59], a simple method for the estimation of the times of pion and kaon maximal emission, based on the particle p T spectra and the dependencies of longitudinal femtoscopy radii R long on the pair transverse mass m T , was proposed and tested in simulations within the different versions of the (integrated) hydrokinetic model [52,60]. Soon after the first of the mentioned publications, the proposed prescription was used by the ALICE Collaboration in their experimental analysis of kaon femtoscopy for the 2.76 TeV Pb + Pb collisions at the LHC [61].…”

“…In the current paper, we tried to investigate the process of pion and kaon emission considered in [57,59] in more detail, clarify the relationship between the extracted emission times and the femtoscopy radii, and if possible, propose a way for the estimation of the full system's lifetime, including the afterburner stage, based on our analysis of ultrarelativistic heavy-ion collisions within the integrated hydrokinetic model.…”

The analysis of the spatiotemporal picture of particle radiation in relativistic heavy-ion collisions in terms of correlation femtoscopy scales, emission, and source functions allows one to probe the character of the evolution of the system created in the collision. Realistic models, such as the integrated hydrokinetic model (iHKM), used in the present work, are able to simulate the entire evolution process of strongly interacting matter produced in high-energy nuclear collisions. The mentioned model describes all the stages of the system’s evolution, including thermalisation and hydrodynamisation, which can help researchers figure out the specific details of the process and better understand the formation mechanisms of certain observables. In the current paper, we investigated the behaviour of the pion and kaon interferometry radii and their connection with emission functions in ultrarelativistic heavy-ion collisions at the Large Hadron Collider within iHKM. We focused on the study of the emission time scales at different energies for both particle species (pions and kaons) aiming to gain deeper insight into relation of these scales and the peculiarities of the mentioned system’s collective expansion and decay with the experimentally observed femtoscopy radii. One of our main interests was the problem of the total system’s lifetime estimation based on the femtoscopy analysis.
