The Last Heavy Lepton and The Next One

The present leptonic SU2 × U1 weak interaction theory was formulated in 1967 (Ref. 1), ten years after the familiar V-A theory (Ref. 2). A decade later still, the low energy limit of this theory is now the successor to the V-A theory (Ref. 3). A brief explanation of why this is so (and why I will not discuss models) is in order. Most of us believe that charged current interactions are mediated by exchange of a massive charged vector boson (Ref. 1,2). In the low energy limit the V-A fheory with eμ universality results.

    The plot is from ref. (4), modified slightly. In SU2 × U1 gauge models gA has to change in half-units. Only the “standard” model is allowed by the figure, since gA ≈- 1/2.Google Scholar

    From J. Ellis et al., Nucl.Phys. B131 (1977) 285 Strictly speaking, θ′, θ″ < θc hold in a 6-quark, 6-lepton model without σ. But the limits are probably more general.Google Scholar

    The argument presented here is a heuristic one. It is, of course, hardly clear that leptons and quarks remain pointlike even if they have very large mass. One can only try to motivate a search for mass regularities.Google Scholar

    Suppose there are very many fermion flavors. Then we also expect many “neutrinos” νe, νμ, ντ ... νn ... . Probably most (if not all) are massive. If their masses follow the pattern of e, μ, τ we would expect a lot of them (of order 10′ or so) within the mass range up to a few GeV. They will mix with one another and decay (as b, s do). For νn lifetime τ 10-9 the signatures at PETRA are where l±, ν stands for any charged or neutral lepton of mass <Inline>1</Inline> . Since most of these decay too, many e±± can result.Google Scholar
