“…Since the (phase) transition from hadrons to quarks might take place only in a small sub-volume and for a short timespan compared to the overall process of the heavy ion collisions (HICs), it is an intricate but essential task to explore the space-time structure of the region of homogeneity in HICs. Fortunately, a well-established technique called Hanbury-Brown-Twiss interferometry (HBT) [1,2,3] has been developed, which is now extensively used in the heavy-ion community to determine the space-time dimensions of the particle emission source for HICs with energies from SIS to RHIC [4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35]. Studies on various species of two-particles other than identical charged pions have been published or are being pursued (see, e.g.…”
