Abstract
There is now a consistent body of evidence, which points towards the following fundamental building blocks of matter:
i) Three doublets of leptons:
charge | |||
---|---|---|---|
0 -1 | ve e- | vμ μ- | vτ τ- |
The τ neutrino vτ has not been directly observed, but information on the τ decays makes its existence very likely.1,2
ii) Five (possibly six)3 flavors of quarks, which can again be arranged in three doublets according to their charge:
charge | |||
---|---|---|---|
2/3 -1/3 | u d | c s | t* b |
