However, conventional SL (unflavoured) requires an unnaturally small soft supersymmetry(SUSY)-breaking bilinear $B \\ll \\mathcal{O}({\\rm TeV})$ coupling for successful leptogenesis. On the other hand, in this regime, the interactions mediated by $\\tau$, $\\mu$ (and even $e$) charged lepton Yukawa interactions are in equilibrium, making the lepton number asymmetries and the washouts flavour dependent. Hence, it is crucial to take into account the flavour effects.
