| contents | Langevin Dynamics of the Deconfinement Transition for Pure Gauge Theory Ana Júlia Mizher Eduardo S. Fraga Gastão Krein Física, Astronomía y Matemáticas Quark gluon plasma Deconfinement Spinodal decomposition Dynamics of phase transitions We investigate the effects of dissipation in the deconfinement transition for pure SU(2) and SU(3) gaugetheories. Using an effective theory for the order parameter, we study its Langevin evolution numerically. Noiseeffects are included for the case of SU(2). We find that both dissipation and noise have dramatic effects on thespinodal decomposition of the order parameter and delay considerably its thermalization. For SU(3) the effectsof dissipation are even larger than for SU(2). 2007 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46437422 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.2B Vol.37 |
