Sumbera Física, Astronomía y Matemáticas Heavy ions Femtoscopy Using recent high-statistics STAR data from Au+Au and Cu+Cu collisions at full RHIC energy I discussstrong and Coulomb-induced final state interaction effects on identical (π−π) and non-identical (π−Ξ) particlecorrelations. Analysis of π−Ξ correlations reveals the strong and Coulomb-induced FSI effects, allowing for thefirst time to estimate spatial extension of π and Ξ sources and the average shift between them. Source imagingtechniques provide clean separation of details of the source function and are applied to the one-dimensional relativemomentum correlation function of identical pions. For low momentum pions, and/or non-central collisions,a large departure from a single-Gaussian shape is observed. 2007 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46437609 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.3A Vol.37 |
