Abstract
A simple and economical extension of the minimal standard electroweak gauge model (without right-handed neutrinos) by the addition of two he avy Higgs scalar triplets would have two significant advantages. Natur ally small Majorana neutrino masses would become possible, as well as leptogenesis in the early universe which gets converted at the electro weak phase transition into the present observed baryon asymmetry.
