A study of the parity-odd nucleon-nucleon potential

Understand

We investigate the parity-violating nucleon-nucleon potential as obtained in chiral effective field theory.

• By using resonance saturation we compare the chiral potential to the more traditional one-meson exchange potential.
• In particular, we show how parameters appearing in the different approaches can be compared with each other and demonstrate that analyses of parity violation in proton-proton scattering within the different approaches are in good agreement.
• In the second part of this work, we extend the parity-violating potential to next-to-next-to-leading order.
