Pion Transverse Momentum Spectrum, Elliptic Flow, and Interferometry in the Granular Source Model for RHIC and LHC Heavy Ion Collisions

Figure 2

(Color online) the results of pion HBT radii and chaoticity parameter of the granular sources (open circle) with different centralities for the highest RHIC energy (left column) and LHC energy (right column). The solid circle, star, and solid diamond symbols in the left column are the STAR data of the Au-Au collisions at  GeV with 0–5%, 10–20%, and 30–50% centralities [12], respectively. The star and solid triangle-down symbols in the right column are the ALICE data of the Pb-Pb collisions at  TeV with 10–20% and 40–50% centralities [25], respectively.
