The standard model is a theoretical framework describing the behaviour of elementary quarks and leptons as a result of strong and electroweak interactions. Our current understanding of the production and decay properties of the W ± and Z 0 particles, the exchange bosons of the weak interaction, will be described and the striking agreement of these properties with predictions of the standard model will be emphasized.

We present a detailed calculation of the Lagrangian of the standard model prescribed in the paper [4] of Connes and Lott, first for the electroweak interactions alone, and then (as is necessary to achieve the correct weak hypercharge assignments) for the coupling of electroweak interactions with chromodynamics. In its most symmetrical form (with free parameters the fermion mass-matrices plus one universal coupling constant), the Connes theory in tree-approximation yields equality of the strong and electroweak coupling constants, and fixes the value sin 2 θw = 3/8, and the ratios mt/mw and mH/mt.
