On a redundancy in the parity-violating 2-nucleon contact Lagrangian
arXiv:0804.0772 · doi:10.1103/PhysRevC.77.067001
Abstract
It is shown that the number of independent operators in the nucleon-nucleon parity-violating contact Lagrangian at the leading order in the low-momentum expansion, can be reduced to five, by using Fierz rearrangements of the nucleon fields.
