Aspects of phi-meson production in proton-proton collisions
A. Sibirtsev, J. Haidenbauer, U. -G. Meißner
We analyze near-threshold cross section data for the reaction pp->pp phi published by the DISTO collaboration and recent, still preliminary results presented by the ANKE Collaborat…
Towards a field theoretic understanding of NN->NNpi
V. Lensky, V. Baru, J. Haidenbauer +3
We study the production amplitude for the reaction NN->NNpi up to next--to--leading order in chiral perturbation theory using a counting scheme that takes into account the large sc…
KKbar photoproduction from protons
A. Sibirtsev, J. Haidenbauer, S. Krewald +2
We study the contribution of the Drell mechanism driven by K^+ and K^- exchange to the reaction gamma N -> KKbar N. Our calculation implements the full KN and KbarN reaction amplit…
The K^- αscattering length and the reaction dd \to αK^+ K^-
V. Yu. Grishina, L. A. Kondratyuk, A. Sibirtsev +4
We present predictions for the the K^- αscattering length obtained within the framework of the multiple scattering approach. Evaluating the pole position of the K^- αscattering amp…
