| contents | Source Chaoticity in Relativistic Heavy Ion Collisions at SPS and RHIC Shin Muroya Hiroki Nakamura Kenji Morita Física, Astronomía y Matemáticas Pion interferometry Relativistic heavy ion collisions We investigate degree of coherence of pion sources produced in relativistic heavy ion collisions using multiparticleinterferometry. In order to obtain true chaoticity, ltrue from two-pion correlation functions measuredin experiments, we make a correction for long-lived resonance decay contributions. Using this ltrue and theweight factor which are obtained from parameter fitted to two- and three-pion correlation function, we calculatea chaotic fraction e and the number of coherent sources a for different colliding energies. The resultgives constraints on the source and shows an increase of the minimum number of a with multiplicity, althoughmultiplicity independent chaoticity is not excluded. 2007 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46437506 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 |
