Mass-spectrum of Charged Leptons from the Planck Mass

There are three generations of charged leptons - the electron, muon, and tau. Masses of elementary particles are considered as fundamental constants. Modern physics believes these masses could be calculated from more fundamental mass scale, e.g., the Planck mass. Scientists seek for such relationship for many years. However, a relation between mass-spectrum of charged leptons and the Planck mass is still unknown. Here we show a way to derive the mass-spectrum of charged leptons from the Planck mass.
