Web29 sep. 2024 · For particles with mass, helicity isn't a good quantum number. So, it doesn't have to be conserved. So, if helicity is not a good quantum number for massive particles and in the massless case helicity is the same as chirality, why do we need helicity in the first place. Why don't we just use chirality? eys_physics said: Web14 apr. 2024 · Supramolecular chiral emergence from achiral molecules is studied with amphiphilic polypeptides upon forming molecular assemblies of nanosheets and vesicles …
