DOI: 10.1007/s00601-018-1409-4
Abstract: QCD is not supersymmetrical in the traditional sense—the QCD Lagrangian is based on quark and gluonic fields, not squarks nor gluinos. However, its hadronic eigensolutions conform to a representation of superconformal algebra, reflecting the underlying… read more here.
