Abstract: | Electroweak parity violating interaction between supernova (SN) neutrinos and electrons of a simple chiral molecule is studied
related to the origin of molecular homochirality. Appearance of supernova remnants inside molecular clouds favours the interaction
of SN-neutrinos with interstellar molecules, leading to a energetic difference between the two enantiomers of the order of
10–5 eV. This energetic difference is closer to the thermic energy of the interstellar medium, so molecular homochirality could
be enhanced in molecular clouds containing supernova remnants inside it due to neutrino interaction. |
