      Global horizontal symmetry

    • Abstract

       

      It is pointed out that the present SU(3)c×SU(2)L×U(1) gauge interactions with three families have a global horizontal symmetry (denoted hereby SU(3)H) which is broken only by the weak charged hadron currentJh. Also, with (u, c), (d, s), (ve, {ie437-1}) and (e−,μ−) as doublets of SU(2)H (subgroup of SU(3)H),Jh has simple transformation properties under this subgroup. Amplitude relations, using SU(2)H symmetry, for hadronic leptonic and semileptonic decays are given.
