“…Previous kaon femtoscopy studies carried out in Pb-Pb collisions at the CERN Super Proton Synchrotron (SPS) by the NA44 and NA49 Collaborations [22,23] reported the decrease of R long with m T as ∼m −0.5 T as a consequence of the boost-invariant longitudinal flow. Subsequent studies carried out in Au-Au collisions at RHIC [24][25][26][27] have shown the same power in the m T dependencies for π and K radii, consistent with a common freeze-out hypersurface. Like in the SPS data, no exact universal m T scaling for the three-dimensional (3D) radii was observed at RHIC, but still these experiments observed an approximate m T scaling for pions and kaons.…”

We present the results of three-dimensional femtoscopic analyses for charged and neutral kaons recorded by ALICE in Pb-Pb collisions at √ s NN = 2.76 TeV. Femtoscopy is used to measure the space-time characteristics of particle production from the effects of quantum statistics and final-state interactions in two-particle correlations. Kaon femtoscopy is an important supplement to that of pions because it allows one to distinguish between different model scenarios working equally well for pions. In particular, we compare the measured three-dimensional kaon radii with a purely hydrodynamical calculation and a model where the hydrodynamic phase is followed by a hadronic rescattering stage. The former predicts an approximate transverse mass (m T ) scaling of source radii obtained from pion and kaon correlations. This m T scaling appears to be broken in our data, which indicates the importance of the hadronic rescattering phase at LHC energies. A k T scaling of pion and kaon source radii is observed instead. The time of maximal emission of the system is estimated by using the three-dimensional femtoscopic analysis for kaons. The measured emission time is larger than that of pions. Our observation is well supported by the hydrokinetic model predictions.

The main features of femtoscopy measurements in heavy-ion collisions at high energies are understood as a manifestation of the strong collective flow and well-interpreted within hydrodynamic models with a crossover. In this work, we discuss possibilities for observing the change from a first order phase transition expected at the NICA energies (√ s N N = 4-11 GeV) to a crossover one with the femtoscopy observables using the vHLLE+UrQMD model.

“…It is necessary to mention that α is almost constant for the radii R long , because the radial flow does not affect the longitudinal radii. The drop of R long is mainly caused by the longitudinal flow and the longitudinal direction of the source is satisfied with the boostinvariant in the THERMINATOR model [11,17]. Figure 4 shows the HBT radii from the directly freeze-out pions and the pions with resonance decay for different v T .…”

Using the Blast-Wave parameterized model in THERMINATOR 2, we study the effect of the radial flow and resonance decay on the transverse momentum dependence of HBT parameters for Au+Au central collisions at the RHIC energy √ s N N = 200 GeV. The results indicate that the radial flow directly affects the space-momentum correlations and the dependence of the transverse HBT radii on transverse momentum. The rise of α with increasing v T for R out is faster than that for R side which suggests that R out is more susceptible to the radial flow. The pions decayed from resonance increase the HBT radii and strengthen the negative dependence of the radii on transverse momentum.
