(a) Product of the three pion HBT radii at 𝑘_𝑇 (average transverse momenta of two pions) =0.3 GeV/c for central heavy-ion collisions at AGS [68], SPS [69, 70], RHIC [71, 72], and LHC [73] energies. (b) The decoupling time extracted from 𝑅_long(𝑘_𝑇) for central heavy-ion collisions at midrapidity at AGS, SPS, RHIC, and LHC energies as a function of (𝑑𝑁_ch/𝑑𝜂)^1/3.
