Three-pion hanbury browntwiss correlations in relativistic heavy-ion collisions from the star experiment Academic Article uri icon

abstract

  • Data from the first physics run at the Relativistic Heavy-Ion Collider at Brookhaven National Laboratory, [Formula presented] collisions at [Formula presented], have been analyzed by the STAR Collaboration using three-pion correlations with charged pions to study whether pions are emitted independently at freeze-out. We have made a high-statistics measurement of the three-pion correlation function and calculated the normalized three-particle correlator to obtain a quantitative measurement of the degree of chaoticity of the pion source. It is found that the degree of chaoticity seems to increase with increasing particle multiplicity. 2003 The American Physical Society.
