    "abstract": "We consider the correlation between the binding energies of the triton and\nthe alpha-particle which is empirically observed in calculations employing\ndifferent phenomenological nucleon-nucleon interactions. Using an effective\nquantum mechanics approach for short-range interactions with large scattering\nlength |a| \u003e\u003e l, where l is the natural low-energy length scale, we construct\nthe effective interaction potential at leading order in l/|a|. In order to\nrenormalize the four-nucleon system, it is sufficient to include a\nSU(4)-symmetric one-parameter three-nucleon interaction in addition to the\nS-wave nucleon-nucleon interactions. The absence of a four-nucleon force at\nthis order explains the empirically observed correlation between the binding\nenergies of the triton and the alpha-particle. We calculate this correlation\nand obtain a prediction for the alpha-particle binding energy. Corrections to\nour results are suppressed by l/|a|.",
