Comments on the leptonic couplings of the ψ(3.1 GeV) resonance

  • Published:
Lettere al Nuovo Cimento (1971-1985)

Conclusion

As discussed previously, taking the dip which is seen in the e+e− data about 1 MeV below the peak at its face value, one is led to demand a large total width which however cannot now be attributed to known leptonic channels. The problem of the destructive interference before the resonance can be partially understood provided one employs a negative-metric boson of the Lee-Wick type. Also, the charge asymmetry in μ+μ- channel as observed requires one to relax the pureV-A structure and thus give up chirality. Lastly, the possibility of spin other than 1 is still open. We hope to return to these problems elsewhere.
