Gauge Theory of Weak and Electromagnetic Interactions with Han-Nambu Quarks

Abstract
The use of Han-Nambu quarks enables us to construct an SO(3) gauge theory of weak and electromagnetic interactions which is compatible with the naive quark model. The model is constrained by the requirements that KLμμ¯ is suppressed and the KLKS mass splitting is small. This leads to a relation between the W mass and the Cabibbo angle, which determines the W mass to be near 35 GeV.
