DOI: 10.1007/jhep01(2025)077
Abstract: We discuss a QCD-scale composite axion model arising from dark QCD coupled to QCD. The presently proposed scenario not only solves the strong CP problem, but also is compatible with the preheating setup for the… read more here.

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.
