Description
A complete classification of all the spin-flavor structures that cancontribute to three-nucleon forces is presented and their power counting in 1/Nc is discussed. Including all independent momentum structures, a complete basis of operators for the three-nucleon force is given explicitlyi up to next-to-leading order inthe 1/Nc expansion. It is also shown that the expansion is in a power series in 1/Nc^2.
