Abstract

Connes' gauge theory on M-4 x Z(2) is reformulated in the Lagrangian level. It is pointed out that the field strength in Connes' gauge theory is not unique. We explicitly construct a field strength different from Connes' andprove that our definition leads to the generation-number independent Higgspotential. It is also shown that the nonuniqueness is related to the assumption that two different extensions of the differential geometry are possible when the extra one-form basis x is introduced to define the differentialgeometry on M4 x Z2. Our reformulation is applied to the standard model based on Connes' color-flavor algebra. A connection between the unimodularitycondition and the electric charge quantization is then discussed in the presence or absence of nu (R).
