Description
A study of the energy behavior of the hadronic spectra and pion
interferometry scales is conducted for the top SPS, RHIC and LHC
energies within the hydrokinetic approach. The latter allows one
to describe evolution of quark-gluon and hadron matter as well as
continuous particle emission from the fluid in agreement with the
underlying kinetic equations. The main mechanisms that lead to the
paradoxical, at first sight, behavior of the interferometry
scales, are exposed. In particular, a decrease of
$R_{out}/R_{side}$ ratio with growing energy happens due to
pre-thermal collective transverse flows and a strengthening of
positive correlations between space and time positions of emitted
pions. Also the results obtained within hydrokinetic model as for kaon intensity interferometry at RHIC are presented.
