Composite neutrinos and baryogenesis identity

Excited leptons that share the lepton numbers with the Standard Model leptons, but have larger masses, are predicted in the theories of compositeness. I will discuss the bounds on the excited neutrino masses that are still allowed to be of order 1 TeV. Then I will introduce possible generation of the baryon asymmetry of the universe using these new particles. The discussed baryogenesis does not contradict to the small masses of the observable neutrinos and the proton stability.
