- Title
Meson production in nucleon-nucleon collisions.
- Authors
Haidenbauer, J.
- Abstract
I review some recent works on meson production in nucleon-nucleon collisions. In particular, I report on an investigation of the reaction NN → NNπ near threshold where the production amplitude has been evaluated within chiral perturbation theory up to next-to-leading order, using a counting scheme that takes into account the large scale introduced by the initial momentum. With regard to other meson-production reactions I focus on a phenomenological analysis of the Λ/Σ0 production ratio in pp collisions.
