We measure the general scaling laws relating the particle-loss and heating rates to the temperature, scattering length, and atom number. Both at unitarity and for positive $a \\ll \\lambda$ we find agreement with three-body theory. However, for $a<0$ and away from unitarity, we observe significant four-body decay. At unitarity, the three-body loss coefficient, $L_3 \\propto \\lambda^4$, is three times lowe","authors_text":"Alexander L. Gaunt, Nir Navon, Richard J. Fletcher, Robert P.
