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.
