DESCRIPTION:If leptogenesis occurs in the medium (low) temperature regime 
 $T\\lsim 10^{12}$ GeV ($\\lsim 10^{9}\\\,$ GeV) where the rates of process
 es mediated by the $\\tau$ (and $\\mu$) Yukawa coupling are non negligible
 \, lepton flavors dynamics can have surprising effects on the generation o
 f cosmic asymmetries: (i) The baryon asymmetry can be enhanced by up to on
 e order of magnitude\; (ii) The sign of the asymmetry can be opposite to w
 hat one would predict from the sign of the total lepton asymmetry $\\epsil
 on_1$\; (iii) Successful leptogenesis is possible even when the total lept
 on asymmetry in the heavy neutrinos decays vanishes ($\\epsilon_1=0$). We 
 discuss these effects\, and we also comment on additional corrections from
  Higgs effects and sphalerons processes.\n\nhttps://indico.ific.uv.es/even
