Anomalous Diffusion of Pions at RHIC M. Csanád M. Nagy T. Csörgo Física, Astronomía y Matemáticas Femtoscopy Correlations Rescattering Anomalous diffusion Stable distributions After pointing out the difference between normal and anomalous diffusion, we consider a hadron resonancecascade (HRC) model simulation for particle emission at RHIC and point out that rescattering in an expandinghadron resonance gas leads to a heavy tail in the source distribution. The results are compared to recent PHENIXmeasurements of the tail of the particle emitting source in Au+Au collisions at RHIC. In this context, we showhow can one distinguish experimentally the anomalous diffusion of hadrons from a second order QCD phasetransition. 2007 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46437618 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
