Gay Ducati Física, Astronomía y Matemáticas Traveling waves Transition to saturation It has been shown that the transition to the saturation regime of high energy QCD is similar to the formationof the front of a traveling wave. In particular, it can be verified that Balitsky-Kovchegov (BK) evolution equationreduces, after some approximations, to the nonlinear Fisher and Kolmogorov-Petrovsky-Piscounov (FKPP)equation, well-known from statistical physics. In these proceedings, based on the current knowledge of theasymptotic solutions of the BK equation, we propose a parametrization for the forward scattering amplitudewhich interpolates between the traveling wave solution and the saturation region. 2007 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46437432 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 |
