ANOMALY FREEDOM THROUGH LEPTO-QUARK MATTER
Subhash Rajpoot · Modern Physics Letters A · 1990
Lepto-quark matter represents new fermionic matter that carries quark as well as lepton numbers. An extension of the standard model with three families of conventional quarks and leptons is presented in which freedom from anomalies is secured through the presence of lepto-quark matter representations. The gauge symmetry of the model is SU(2)L×U(1)q×U(1)l where U(1)q and U(1)l refer to distinct hypercharge sources for the quarks and the leptons.
