The three-dimensional pion and kaon emission source functions are extracted from the HKM model simulations of the central Au+Au collisions at the top RHIC energy $\sqrt{s_{NN}}=200$ GeV. The model describes well the experimental data, previously obtained by the PHENIX and STAR collaborations using the imaging technique. In particular, the HKM reproduces the non-Gaussian heavy tails of the source function in the pair transverse momentum (out) and beam (long) directions, observed in the pion case and practically absent for kaons. The role of the rescatterings and long-lived resonances decays in forming of the mentioned long range tails is investigated. The particle rescatterings contribution to the out tail seems to be dominating. The model calculations also show the substantial relative emission times between pions (with mean value 14.5 fm/c in LCMS), including those coming from resonance decays and rescatterings. The prediction is made for the source functions in the LHC Pb+Pb collisions at $\sqrt{s_{NN}}=2.76$ TeV, which are still not extracted from the measured correlation functions.

Original abstract

The three-dimensional pion and kaon emission source functions are extracted from the HKM model simulations of the central Au+Au collisions at the top RHIC energy $\sqrt{s_{NN}}=200$ GeV. The model describes well the experimental data, previously obtained by the PHENIX and STAR collaborations using the imaging technique. In particular, the HKM reproduces the non-Gaussian heavy tails of the source function in the pair transverse momentum (out) and beam (long) directions, observed in the pion case and practically absent for kaons. The role of the rescatterings and long-lived resonances decays in forming of the mentioned long range tails is investigated. The particle rescatterings contribution to the out tail seems to be dominating. The model calculations also show the substantial relative emission times between pions (with mean value 14.5 fm/c in LCMS), including those coming from resonance decays and rescatterings. The prediction is made for the source functions in the LHC Pb+Pb collisions at $\sqrt{s_{NN}}=2.76$ TeV, which are still not extracted from the measured correlation functions.

Recent simulations of the kaon source function [ref] with the hydrokinetic model (HKM) [ref] show a good agreement in the side direction, although it is slightly over the measurements at larger radii in out and long (downward-pointing triangles).

For the case of Au+Au collisions at $√(s)= 200$ GeV we take the parameters from [ref] corresponded to the best fit for the pion, kaon and proton spectra and pion interferometry data, $ϵ_0 = 430$ GeV/fm$^3$ and $α= 0.45$ fm (the maximal initial transverse velocity at the very periphery of the system is then 0.05).

We use this particular variant in the current analysis, relying on the result of [ref] , where the comparison of one- and two-particle spectra, calculated at both types of matching hydro and cascade stages, showed a quite small difference between them in the considered case of top RHIC and LHC energies.
