Kaon femtoscopy with Lévy-stable sources from GeV collisions at RHIC
arXiv:2306.13668 · doi:10.3390/universe9070300
Abstract
Femtoscopy has the capacity to probe the space-time geometry of the particle-emitting source in heavy-ion collisions. In particular, femtoscopy of like-sign kaon-pairs may shed light on the origin of non-Gaussianity of the spatial emission probability density. The momentum-correlations between like-sign kaon-pairs are, hence, measured in data recorded by the STAR experiment, from GeV collisions at RHIC, BNL. Preliminary results hint at the, possible, existence of non-Gaussian, Lévy-stable sources; and signal the, likely, presence of an anomalous diffusion process; for the identically-charged kaon-pairs so produced. More statistically significant studies, at lower centre-of-mass energies, may contribute to the search for the critical end point of QCD as well.
