Analyses of multi-pion Bose-Einstein correlations for granular sources with coherent pion-emission droplets *

Abstract The ALICE Collaboration measured three- and four-pion Bose-Einstein correlations (BECs) for Pb-Pb collisions at the Large Hadron Collider (LHC). It is speculated that observed significant suppression of multi-pion BECs owing to a considerable degree coherent pion emission in these collisions. Here, we study BEC functions granular sources with pion-emission droplets. We find intercepts correlation relative momenta near zero are sensitive number droplets source. They decrease droplet number. three-pion evolving momentum-dependent partially basically agree experimental data TeV LHC. However, model results function inconsistent data. Investigations into normalized suggest an interesting enhancement moderate relative-momentum region.
