Quark masses and cabibbo angles
Abstract
A simple symmetric pattern of Higgs fields in an SU (2) L × SU (2) R × U (1) gauge model with six quarks yields: tan 2θc = md/ ms and θc = 15° in good agreement with experiment. A eight-quark extension of the model leads to successful determination of the three Cabibbo-like angles connecting the first six quarks and to the prediction mt ∼ 9.3 mc ∼ 14 GeV.
