Hanbury Brown--Twiss Interferometry and Collectivity in Small Systems
Christopher Plumberg
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 K T and the system charged multiplicity dN ch /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… Show more
