  • DistortedWave Emission Function (DWEF) Calculations of RHIC HBT and Spectra John G. Cramer Gerald A. Miller Física, Astronomía y Matemáticas Optical model Chiral symmetry restoration Distorted wave emission function Relativistic heavy ion collisions The emission of pions produced within a dense, strongly-interacting system of matter in the presence of strongradial flow and absorption is described using a relativistic optical model formalism, replacing the attenuated orunattenuated plane waves of earlier emission function approaches with “distorted wave” solutions to a relativisticwave equation including a complex optical potential. The resulting distorted-wave emission function model(DWEF) is used in numerical calculations to fit HBT correlations and the resonance-corrected pion spectrumfrom central-collision STAR Au+Au pion data at √s = 200 GeV. Excellent agreement with the STAR data areobtained. This allows us to predict HBT radii over a range of centralities for both Au+Au and Cu+Cu collisions. 2007 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46437610 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
