轻子和强子的普遍强、弱和电磁相互作用是通过测量基本对称结构$\mathrm{SU}{(4)}_{L}\ifmmode\times\else\texttimes\fi{}\mathrm{SU}{(4)}_{R}\ifmmode\times\else\texttimes\fi{}\mathrm{SU}({4}^{\ensuremath{‘}})$，的非阿贝尔可重正无反常子群而产生的，该基本对称结构将三个四重重子夸克和四个已知轻子合并成16重手征费米子多重态，轻子数被视为第四个“色”量子数。讨论了该方案的实验结果。这包括(1)同时携带重子和轻子量子数的奇异规范介子的出现和影响，特别是在半轻子过程中；(2)在高能下轻子和半轻子过程之间反常强相互作用的表现；(3)夸克和质子衰变中重子-轻子数破坏的独立可能性；以及(4)(V+A)弱电流效应的发生。
Universal strong, weak, and electromagnetic interactions of leptons and hadrons are generated by gauging a non-Abelian renormalizable anomaly-free subgroup of the fundamental symmetry structure $\mathrm{SU}{(4)}_{L}\ifmmode\times\else\texttimes\fi{}\mathrm{SU}{(4)}_{R}\ifmmode\times\else\texttimes\fi{}\mathrm{SU}({4}^{\ensuremath{'}})$, which unites three quartets of "colored" baryonic quarks and the quartet of known leptons into 16-folds of chiral fermionic multiplets, with lepton number treated as the fourth "color" quantum number. Experimental consequences of this scheme are discussed. These include (1) the emergence and effects of exotic gauge mesons carrying both baryonic as well as leptonic quantum numbers, particularly in semileptonic processes, (2) the manifestation of anomalous strong interactions among leptonic and semileptonic processes at high energies, (3) the independent possibility of baryon-lepton number violation in quark and proton decays, and (4) the occurrence of ($V+A$) weak-current effects.
