Charges

Properties of charges in general are discussed and it is shown that, whatever the nature of the charge considered, its value for any elementary particle can be deduced from the corresponding values for a minimum number of such particles, namely 3. This leads to the introduction of a "charge-space" which, in the present state of our knowledge, is three-dimensional. Examples are given. The "neutrinonic charge" which is to the neutrino what the electric charge is to the electron is especially studied. Correlations between charges and between charges and S and T3 are discussed.
