Abstract

It is shown via a large series of numerical tests on two fundamental organic molecules, the L-a-amino acidL-valine and the sugar precursor hydrated D-glyceraldheyde, that the ab initio calculation of the parityviolatingenergy shift, at the random-phase approximation level of accuracy, provides results that are about oneorder of magnitude larger than those obtained by means of less accurate methods employed previously. Thesefindings would make more plausible the hypothesis of electroweak selection of natural enantiomers via theKondepudi-Nelson scenario, or could imply that Salam phase-transition temperature is higher than previouslyinferred: accordingly, the hypothesis of terrestrial origin of life would become more realistic.
