“…The hydrodynamic predictions [2] for p T behavior of the radii at the LHC energies were confirmed by the ALICE experiment [3]. The most impressive hydrodynamic prediction [4,5], that the ratio of the two transverse interferometry radii, out to side, will drop in the whole p T -interval with increasing collision energy and reaches a value close to unity at the LHC, has been discovered experimentally [3]. Now the hydrodynamic-based approach to ultrarelativistic nucleus-nucleus collisions becomes the "standard model" for these processes.…”

Uniform description of bulk observables in the hydrokinetic model ofA+Acollisions at the BNL Relativistic Heavy Ion Collider and the CERN Large Hadron Collider

A simultaneous description of hadronic yields; pion, kaon, and proton spectra; elliptic flows; and femtoscopy scales in the hydrokinetic model of A+A collisions is presented at different centralities for the top BNL Relativistic Heavy Ion Collider (RHIC) and CERN Large Hadron Collider (LHC) 2.76-TeV energies. The initial conditions are based on the Glauber Monte-Carlo simulations. When going from RHIC to LHC energy in the model, the only parameters changed are the normalization of the initial entropy defined by the number of all charged particles in most central collisions, contribution to entropy from binary collisions and barionic chemical potential. The hydrokinetic model is used in its hybrid version (hHKM), which provides the correct match (at the isochronic hypersurface) of the decaying hadron matter evolution with hadronic ultrarelativistic quantum molecular dynamics cascade. The results are compared with the standard hybrid models where hydrodynamics and hadronic cascade are matching just at the non-space-like hypersurface of chemical freeze-out or on the isochronic hypersurface. The modification of the particle number ratios at LHC caused, in particular, by the particle annihilations at the afterburn stage is also analyzed.

“…The agreement of this quality cannot be achieved with the initial condition obtained from the typically used Glauber models. In that case the HBT radii, in particular the ratio of out to side radii, is reproduced only at the level of 20% [29]. The reader is referred to Ref.…”

Azimuthally sensitive femtoscopy for heavy-ion collisions at the Relativistic Heavy Ion Collider (RHIC) and Large Hadron Collider (LHC) is explored within the approach consisting of the hydrodynamics of perfect fluid followed by statistical hadronization. It is found that for the RHIC initial conditions, employing the Gaussian shape of the initial energy density, the very same framework that reproduces the standard soft observables [including the transverse-momentum spectra, the elliptic flow, and the azimuthally averaged Hanbury-Brown-Twiss (HBT) radii] leads to a proper description of the azimuthally sensitive femtoscopic observables; we find that the azimuthal variation of the side and out HBT radii as well as out-side cross term are very well reproduced for all centralities. Concerning the dependence of the femtoscopic parameters on k T we find that it is very well reproduced. The model is then extrapolated to the LHC energy. We predict the overall moderate growth of the HBT radii and the decrease of their azimuthal oscillations. Such effects are naturally caused by longer evolution times. In addition, we discuss in detail the space-time patterns of particle emission. We show that they are quite complex and argue that the overall shape seen by the femtoscopic methods cannot be easily disentangled on the basis of simple-minded arguments.

“…In particular, a sharp phase transition between the color-deconfined and confined states was excluded by the observation of short timescales. Moreover, femtoscopic measurements, together with other observations related to bulk collective flow, provide evidence that a strongly interacting system was created in the collision [12,26,27].…”

Centrality dependence of pion freeze-out radii in Pb-Pb collisions atsNN=2.76 TeV

et al. 2016

We report on the measurement of freeze-out radii for pairs of identical-charge pions measured in Pb-Pb collisions at √ s NN = 2.76 TeV as a function of collision centrality and the average transverse momentum of the pair k T . Three-dimensional sizes of the system (femtoscopic radii), as well as direction-averaged onedimensional radii are extracted. The radii decrease with k T , following a power-law behavior. This is qualitatively consistent with expectations from a collectively expanding system, produced in hydrodynamic calculations. The radii also scale linearly with dN ch /dη 1/3 . This behavior is compared to world data on femtoscopic radii in heavy-ion collisions. While the dependence is qualitatively similar to results at smaller √ s NN , a decrease in the ratio R out /R side is seen, which is in qualitative agreement with a specific prediction from hydrodynamic models: a change from inside-out to outside-in freeze-out configuration. The results provide further evidence for the production of a collective, strongly coupled system in heavy-ion collisions at the CERN Large Hadron Collider.
