Query: Kinetic freeze-out in central heavy-ion collisions between 7.7 and 2760
  GeV per nucleon pair   We fit the single-particle $p_t$ spectra of identified pions, kaons, and
(anti)protons from central collisions of gold or lead nuclei at energies
between 7.7 and 2760~GeV per nucleon pair. Blast wave model with included
resonance production and with an assumption of partial chemical equilibrium is
used and the fits are performed with the help of a Gaussian emulator process. A
kinetic freeze-out temperature is found about 100~MeV for the lowest collision
energies and 80~MeV at the LHC. The average transverse expansion velocity grows
with increasing $\sqrt{s_{NN}}$ from 0.45 to 0.65. Due to partial chemical
equilibrium, the influence of resonance decays on the shape of the $p_t$
spectra for $\sqrt{s_{NN}}$ above 27~GeV is small.
