Abstract:

We use a geomet ric model to study the parameters in the standard model.By using only two parameters we can parametrize all parameters of leptons.The masses computed are in ag reement with the results from experiments.We think that this may lead to a new and profound understanding of the structure of the standard model.We also extend the method to the gauge bosons.The masses obtained by geometric method are also in agreement with experiments.

Key words: lepton model, gauge bosons, fibre bundle, chain volume
