Abstract
We address the few-body problem using the adiabatic hyperspherical representation. A general form for the hyperangular Green’s function in dimensions is derived. The resulting Lippmann-Schwinger equation is solved for the case of three particles with -wave zero-range interactions. Identical particle symmetry is incorporated in a general and intuitive way. Complete semianalytic expressions for the nonadiabatic channel couplings are derived. Finally, a model to describe the atom loss due to three-body recombination for a three-component Fermi gas of atoms is presented.
