• Nucleon-nucleon scattering
• Effective field theory

We analyze parity-violating nucleon-nucleon scattering at energies E < m(pi)(2)/M using the effective field theory appropriate for this regime. The minimal Lagrangian for short-range parity-violating NN interactions is written in an operator basis that encodes the live partial-wave transitions that dominate at these energies. We calculate the leading-order relationships between parity-violating NN asymmetries and the coefficients in the Lagrangian and also discuss the size Of sub-leading corrections. We Conclude with a discussion of further observables needed to completely determine the leading-order Lagrangian.
