Proton-antiproton annihilation into massive leptons and polarization phenomena

Abstract : We extend previous calculations of polarization observables for the annihilation reaction View the MathML source to the case of heavy leptons, such as the μ- and τ-leptons. We consider the case when the beam and/or the target are polarized, as well as when the outgoing leptons are polarized. We give the dependence of the unpolarized cross section, angular asymmetry, and various polarization observables on the relevant kinematical variables in the center of mass and in the laboratory system, paying particular attention to the effect of the mass induced terms.
