K→ππ decays are investigated in the framework of the SU (2)L× U (1) gauge theory of J=0 mesons proposed in Ref. 1, to which is added an interaction between mesons respecting the two symmetries generally attributed to strong interactions, flavor symmetry and parity conservation. It is shown that the damping of the K+→π+π0 amplitude with respect to the ones of Ks→ππ results from a cancellation between the W and Z gauge bosons. The ratio of the two types of amplitudes is sensitive to the spectrum of electroweak (pseudoscalar and scalar) mass eigenstates, and in particular to the mass of the Higgs boson. In the case where scalars and pseudoscalars are degenerate, I demonstrate for the amplitudes the lower bound |Ks→π+π-/ K+→π+π0|≥1/ tan 2θW, where θW is the Weinberg angle.

Many phenomena in elementary particle physics show indications of clustering of two quarks inside baryons. Although the existence of such diquark systems cannot be presently rigorously proven in quantum field theory of strong interactions, phenomenological models require some quark-quark binding to explain effects ranging from the baryon mass spectrum to large pT proton production in high energy pp collisions. This review confronts diquark models predictions with experimental results in low and high transverse momentum hadron-hadron collisions, lepton-nucleon scattering and e+e− annihilations. The recent data from the Split Field Magnet detector on high pT proton production in pp, dd and αα collisions at ISR energies are particularly emphasized.
