Query: On the correlation between the binding energies of the triton and the
  alpha-particle   We consider the correlation between the binding energies of the triton and
the alpha-particle which is empirically observed in calculations employing
different phenomenological nucleon-nucleon interactions. Using an effective
quantum mechanics approach for short-range interactions with large scattering
length |a| >> l, where l is the natural low-energy length scale, we construct
the effective interaction potential at leading order in l/|a|. In order to
renormalize the four-nucleon system, it is sufficient to include a
SU(4)-symmetric one-parameter three-nucleon interaction in addition to the
S-wave nucleon-nucleon interactions. The absence of a four-nucleon force at
this order explains the empirically observed correlation between the binding
energies of the triton and the alpha-particle. We calculate this correlation
and obtain a prediction for the alpha-particle binding energy. Corrections to
our results are suppressed by l/|a|.
