Abstract: (Elsevier)

We formulate the necessary conditions for the survival of the baryon asymmetry generated in the B - L conserving leptoquark decays. We find that equilibrium anomalous electroweak B -non-conserving interactions do not wash out all the baryon asymmetry if (i) there is no mixing in the leptonic sector. (ii) there is large flavour asymmetry in the leptoquark decays, (iii) the mass of the Higgs boson is larger than 56 GeV.
