Melville: Amer Inst Physics, v. 739, p. 640-642, 2004.0094-243Xhttp://hdl.handle.net/11449/23270The back-to-back correlations (BBC) of particle-antiparticle pairs, signalling in-medium mass modification, are studied in a finite size thermalized medium. The width of BBC function is explicitly evaluated in the case of a nonrelativistic spherically symmetric expanding fireball. The effect of the flow is to reduce the BBC signal as compared to the case of non flow. Nevertheless, a significant signal survives finite-time emission plus expansion effects.640-642engExpansion effects on back-to-back correlationsTrabalho apresentado em evento10.1063/1.1843679WOS:000226476000089Acesso aberto0974011233679396
