τ-lepton as a Composition of Massless Preons: an Alternative to Higgs Mechanism

Within the framework of the confinement mechanism proposed earlier by the author in QCD the problem of masses for fundamental fermions in particle physics is discussed by the example of τ-lepton τ−. It is shown that the observed parameters of τ-lepton such as its mass and magnetic moment can be obtained in a preon model dynamically due to a preon gauge interaction. The radius of τ-lepton is also estimated. Under the circumstances preons might be massless in virtue of existence of the nonzero chiral limit for the preon interaction energy.
