Melville: Amer Inst Physics, v. 739, p. 431-433, 2004.0094-243Xhttp://hdl.handle.net/11449/23692Recently there have been suggestions that for a proper description of hadronic matter and hadronic correlation functions within the NJL model at finite density/temperature the parameters of the model should be taken density/temperature dependent. Here we show that qualitatively similar results can be obtained using a cutoff-independent regularization of the NJL model. In this regularization scheme one can express the divergent parts at finite density/temperature of the amplitudes in terms of their counterparts in vacuum.431-433engTrabalho apresentado em evento10.1063/1.1843613WOS:000226476000023Acesso aberto
