Pion reactions on two--nucleon systems

Abstract

We review recent progress in our understanding of elastic and inelastic pion reactions on two nucleon systems from the point of view of effective field theory. The discussion includes pion-deuteron scattering, gamma d to pi-nn, and NN to NNpi. At the end some remarks are made on strangeness production reactions.
