Conservation Law or Violation Law?

An attempt is given, which aims at representing the fundamental laws of weak interactions as conservation laws instead of conventional violation laws. We assume that the conserved quantities characteristic to weak interactions are anti-commutable with those characteristic to strong interactions. All weak interactions are assumed to occur via intermediate boson, which is assumed to belong to an eigenstate of the conserved quantities for weak interactions. V-A law is derived in this way by adopting the chirality as one of the conserved quantities. We adopt also as an conserved quantity the iso-chirality which is defined to be an operator anti-commutable with the iso-parity. Then isospin and hypercharge are not conserved, and |ΔI| =1/2 rule is derived using weak current composed of bilinear forms of quarks. The Cabibbo angle appears naturally in the general definition of the iso-chirality operator. Also briefly discussed is a possible scheme of leptonic interaction, which satisfies the three conditions; |ΔI| =1/2 rule for hadronic processes, non-appearance of neutral lepton currents and universality of coupling constants in the primary interaction between intermediate bosons and weak currents.
