Gauge Theory of Strong, Weak, and Electromagnetic Interactions

Abstract

Starting from the recent U(3) $\otimes$ U(3) gauge model of strong interactions, we discuss the very natural synthesis with Weinberg's model of leptons. As a result of the interplay of the two models (a) neutral $\Delta S=1\mathrm{}$ currents are eliminated without enlarging the number of quarks, and (b) a natural $(3,\overline{3})\oplus (3,\overline{3})$ symmetry breaking emerges for the hadrons. Incorporation of alternative lepton theories is mentioned.
