Few Body Hypernuclear Systems: Weak Decays

  • Carl B. Dover
Part of the Few-Body Systems book series (FEWBODY, volume 2)


The experimental and theoretical situation regarding mesonic and non-mesonic decays of light hypernuclei is reviewed. Although some models give reasonable results for pionic decays as well as the total weak decay rate, no existing approach explains, even qualitatively, the observed spin-isospin dependence of ΛN → NN non-mesonic weak decays.

    I would like to acknowledge discussions with Avraham Gal on this point. The formula (35)reduces to the correct result ΓΛp →npΛn →nn= 2 in the limit where 3S0 widths vanish and 3S1 widths are all equal.Google Scholar
