Hanbury-Brown-Twiss interferometry and collectivity in p+p, p+Pb, and Pb+Pb collisions
(2020) In Physical Review C 102(5).- Abstract
Hanbury Brown-Twiss interferometry (HBT) provides crucial insights into both the space-time structure and the momentum-space evolution of ultrarelativistic nuclear collisions at freeze-out. In particular, the dependence of the HBT radii on the transverse pair momentum KT and the system charged multiplicity dNch/dη may reflect the mechanisms driving collective behavior in small systems. This paper argues that certain features observed in the multiplicity dependence of the HBT radii can be naturally understood if small systems evolve hydrodynamically at high multiplicity. This study thus establishes a baseline for the multiplicity dependence of HBT in hydrodynamics which may prove useful in discriminating between competing models of... (More)
