Few-Body Systems and the Pionless Effective Field Theory

Understand

The pionless effective field theory (EFT) is the appropriate low-energy EFT for short-range interactions that display a large scattering length.

• It has been successfully applied in atomic, nuclear and particle physics.
• We give an overview over recent calculations employing the pionless effective field theory and lay emphasis on applications in the three- and four-body sector where the most exciting developments have occurred.
