Four-nucleon force using the method of unitary transformation
arXiv:0710.4250 · doi:10.1140/epja/i2007-10496-0
Abstract
We discuss in detail the derivation of the leading four-nucleon force in chiral effective field theory using the method of unitary transformation. The resulting four-nucleon force is given in both momentum and configuration space. It does not contain any unknown parameters and can be used in few- and many-nucleon studies.
