Improved action for contact effective field theory
L. Contessi, M. Schäfer, U. van Kolck
We present an improved action for renormalizable effective field theories (EFTs) of systems near the two-body unitarity limit. The ordering of EFT interactions is constrained, but…

Unitary interaction geometries in few-body systems
Lorenzo Contessi, Johannes Kirscher, Manuel Pavon Valderrama
We consider few-body systems in which only a certain subset of the particle-particle interactions is resonant. We characterize each subset by a {\it unitary graph} in which the ver…
