Insights on scalar mesons from their radiative decays
Yu. Kalashnikova, A. Kudryavtsev, A. V. Nefediev +2
We estimate the rates for radiative transitions of the lightest scalar mesons f_0(980) and a_0(980) to the vector mesons rho and omega. We argue that measurements of the radiative…
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…
Can one extract the pi-neutron scattering length from pi-deuteron scattering?
A. Nogga, C. Hanhart
We give a prove of evidence that the original power counting by Weinberg can be applied to estimate the contributions of the operators contributing to the pi-deuteron scattering le…
Extraction of scattering lengths from final-state interactions
A. Gasparyan, J. Haidenbauer, C. Hanhart
A recently proposed method based on dispersion theory, that allows to extract the scattering length of a hadronic two-body system from corresponding final-state interactions, is ge…
