| contents | Evidence for Non-Gaussian Tail in 3-Dimensional Pion Emission Source at SPS P. Chung P. Danielewicz Física, Astronomía y Matemáticas Correlation Interferometry Cartesian harmonics Anisotropic correlation Intensity interferometry The NA49 experiment at CERN SPS has acquired a huge data set of Pb+Pb events over a broad range ofenergy and centrality during the last several years. This high statistics data set, coupled with a state-of-the-artanalysis technique, allows for the first model-independent extraction and energy scan of 3D emission sources forpion pairs at SPS energies. These 3D pion emission sources provide new insights into the nature of a long-rangesource previously reported by PHENIX at RHIC. Preliminary results indicate that the pion source function isessentially Gaussian from 20 AGeV to 80 AGeV but it displays significant non-Gaussian tails at 158 AGeV. 2007 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46437505 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.2C Vol.37 |
