Comments on a novel approach to the role of chirality in the origin of life

Technical Report:

Abstract

We review a recent paper (Salam, 1991a) in which a specific enhancement factor (i.e., a phase transition into a condensed Bose mode) is proposed to account for the observed amplification of the ground state energies of the L- and D-amino acid enantiomers; the difference between these energies is assumed to be due to the neutral parity-violating electroweak interaction. This physical effect initially shifts the enantiomer energies by about 3 x 10{sup -19}eV. The proposed phase transition is characterized by a critical temperature T{sub c}, which may be studied theoretically by enlarging the standard electroweak theory to include either the top quark or supersymmetry (Salam, 1991b). Possible experimental means of finding T{sub c} are discussed. (author). 24 refs, 1 fig.
