WebThe importance of chiral symmetry breaking is a point that e.g. David Gross, a co-father of Quantum Chromodynamics, likes to make whenever some people suggest that the mass is entirely due to the Higgs field. In fact, most of the mass of visible matter is due to the QCD, especially chiral symmetry breaking, and it has nothing to do with the Higgs field. Web4.2: Chiral and Achiral Molecules. Stereoisomers are isomers that differ in spatial arrangement of atoms, rather than order of atomic connectivity.
