| dc.description | We show that an independent four-body momentum scale μ<sub>(4)</sub> drives the tetramer binding energy for fixed trimer energy (or three-body scale μ<sub>(3)</sub>) and large scattering length (a). The three- and four-body forces from the one-channel reduction of the atomic interaction near a Feshbach resonance disentangle μ<sub>(4)</sub> and μ<sub>(3)</sub>. The four-body independent scale is also manifested through a family of Tjon lines, with slope given by μ<sub>(4)</sub>/μ<sub>(3)</sub> for a<sup>−1</sup> = 0. There is the possibility of a new renormalization group limit cycle due to the new scale. |
