Exploratory study of possible resonances in the heavy meson - heavy baryon coupled-channel interactions
Chao-Wei Shen, Deborah Rönchen, Ulf-G. Meißner +1
We use a unitary coupled-channel model to study the interactions. In our calculation, SU(3) flavor symmetry is applied to determine the coupling constan…
Lambda-nuclear interactions and hyperon puzzle in neutron stars
J. Haidenbauer, U. -G. Meißner, N. Kaiser +1
Brueckner theory is used to investigate the in-medium properties of a -hyperon in nuclear and neutron matter, based on hyperon-nucleon interactions derived within SU(3) chiral e…
Eta photoproduction in a combined analysis of pion- and photon-induced reactions
D. Rönchen, M. Döring, H. Haberzettl +3
The final state is isospin-selective and thus provides access to the spectrum of excited nucleons without being affected by excited states. To this end, the world database…
The electromagnetic form factors of the proton in the timelike region
J. Haidenbauer, X. -W. Kang, U. -G. Meißner
The reactions ppbar -> e+e- and e+e- -> ppbar are analyzed in the near-threshold region. Specific emphasis is put on the role played by the interaction in the initial- or final ant…
Photocouplings at the Pole from Pion Photoproduction
D. Rönchen, M. Döring, F. Huang +6
The reactions and are analyzed in a semi-phenomenological approach up to GeV. Fits to differential cross section and single and double polariza…
Coupled-channel dynamics in the reactions piN --> piN, etaN, KLambda, KSigma
D. Rönchen, M. Döring, F. Huang +6
Elastic piN scattering and the world data of the family of reactions pi^- p --> eta n, K^0 Lambda$, K^0 Sigma^0, K^+ Sigma^-, and pi^+ p --> K^+ Sigma^+ are described simultaneousl…
The reaction pi+ p --> K+ Sigma+ in a unitary coupled-channels model
M. Döring, C. Hanhart, F. Huang +3
Elastic pi N scattering and the reaction pi+ p --> K+ Sigma+ are described simultaneously in a unitary coupled-channels approach which respects analyticity. SU(3) flavor symmetry i…
Predictions for the strangeness S=-3 and -4 baryon-baryon interactions in chiral effective field theory
J. Haidenbauer, U. -G. Meißner
The leading order strangeness S=-3 and -4 baryon-baryon interactions are analyzed within chiral effective field theory. The chiral potentials consist of contact terms without deriv…
Strangeness S=-2 baryon-baryon interactions using chiral effective field theory
H. Polinder, J. Haidenbauer, U. -G. Meißner
We derive the leading order strangeness S=-2 baryon-baryon interactions in chiral effective field theory. The potential consists of contact terms without derivatives and of one-pse…
Proposal for the Wide Angle Shower Apparatus (WASA) at COSY-Juelich - "WASA at COSY"
COSY Collaboration, B. Hoistad, J. Ritman
This document describes the physics case, the key experiments proposed and the technical solution for the project "WASA at COSY", which concerns the transfer of the WASA pellet-tar…
