We present a systematic analysis of two-pion interferometry in Au+Au collisions at $\sqrt{s_{\rm{NN}}}$ = 62.4 GeV and Cu+Cu collisions at $\sqrt{s_{\rm{NN}}}$ = 62.4 and 200 GeV using the STAR detector at RHIC. The multiplicity and transverse momentum dependences of the extracted correlation lengths (radii) are studied. The scaling with charged particle multiplicity of the apparent system volume at final interaction is studied for the RHIC energy domain. The multiplicity scaling of the measured correlation radii is found to be independent of colliding system and collision energy.

  1. Tilted geometry of the pion emission source in Au+Au collisions in the RHIC Beam Energy Scan

    nucl-ex 2026-05 unverdicted novelty 7.0

    The pion emission source in Au+Au collisions is tilted with magnitude decreasing rapidly as collision energy rises from 7.7 to 27 GeV, indicating departure from longitudinal boost invariance.

  2. A self-consistent calculation of non-spherical Bose-Einstein correlation functions with Coulomb final-state interaction

    nucl-th 2026-01 unverdicted novelty 6.0

    The authors generalize their prior spherical-source method to non-spherical sources with a self-consistent treatment of Coulomb interactions and provide software for three-dimensional correlation functions.
