Another formalism has recently been developed where particle emission occurs continuously during the whole expansion of thermalized matter. Here we compare both mechanisms in a simplified hydrodynamical framework and show that they lead to a drastically different interpretation of data.331-338engArtigo10.1088/0954-3899/25/2/021WOS:000078694800021Acesso restrito
