The proton decay candidatep→μ+η of Kamioka NDE in Japan, if seriously taken, probably means that fusion is the only mechanism of proton decay. A model based on the work of Pati-Salam-Sarkar is discussed in detail.

Proton decay in theSU(4)c×SU(2)L×SU(2)R model
Possible proton decays in theSU(4)C ×SU(2)L×SU(2)R unification model are discussed. There are some characteristics in the decay products, which are different from those in the standardSU(5) orSO (10)Expand
Unified Interactions of Leptons and Hadrons
Abstract It is suggested that a unifying description of leptons and hadrons can be obtained within a nonabelian gauge theory where the gauge group is a symmetry group of a set of massless elementaryExpand
ΔB = −ΔL, neutron →e−π+, e−K+, μ−π+ and μ−K+ decay modes in SU(2)L × SU(2)R × SU(4)col or SO(10)
Abstract It is stressed that within the simplest model SU(4) of color, unifying quarks with leptons, where B  L is a gauge symmetry, a spontaneous breaking of this symmetry leads naturally toExpand
Unity of All Elementary Particle Forces
Strong, electromagnetic, and weak forces are conjectured to arise from a single fundamental interaction based on the gauge group SU(5).
Lepton Number as the Fourth Color
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 structureExpand
