Hyperon-nuclear interactions from SU(3) chiral effective field theory
Stefan Petschauer, Johann Haidenbauer, Norbert Kaiser +2
The interaction between hyperons and nucleons has a wide range of applications in strangeness nuclear physics and is a topic of continuing great interest. These interactions are no…
Scattering of decuplet baryons in chiral effective field theory
J. Haidenbauer, S. Petschauer, N. Kaiser +2
A formalism for treating the scattering of decuplet baryons in chiral effective field theory is developed. The minimal Lagrangian and potentials in leading-order SU(3) chiral effec…
Density-dependent effective baryon-baryon interaction from chiral three-baryon forces
Stefan Petschauer, Johann Haidenbauer, Norbert Kaiser +2
A density-dependent effective potential for the baryon-baryon interaction in the presence of the (hyper)nuclear medium is constructed, based on the leading (irreducible) three-bary…
Strangeness S=-2 baryon-baryon interaction at next-to-leading order in chiral effective field theory
J. Haidenbauer, Ulf-G. Meißner, S. Petschauer
The strangeness baryon-baryon interaction is studied in chiral effective field theory up to next-to-leading order. The potential at this order consists of contributions from…
Leading three-baryon forces from SU(3) chiral effective field theory
Stefan Petschauer, Norbert Kaiser, Johann Haidenbauer +2
Leading three-baryon forces are derived within SU(3) chiral effective field theory. Three classes of irreducible diagrams contribute: three-baryon contact terms, one-meson exchange…
Hyperons in nuclear matter from SU(3) chiral effective field theory
S. Petschauer, J. Haidenbauer, N. Kaiser +2
Brueckner theory is used to investigate the properties of hyperons in nuclear matter. The hyperon-nucleon interaction is taken from chiral effective field theory at next-to-leading…
Hyperon-nucleon interaction and baryonic contact terms in SU(3) chiral effective field theory
Stefan Petschauer
In this proceeding we summarize results for baryonic contact terms derived within SU(3) chiral effective field theory. The four-baryon contact terms, necessary for the description…
Radiative corrections to the charged pion-pair production process {\boldmath} at low energies
N. Kaiser, S. Petschauer
We calculate the one-photon loop radiative corrections to the charged pion-pair production process . In the low-energy region this reaction is governed by the chi…
SU(3) chiral dynamics and baryon-baryon interactions
Stefan Petschauer
We calculate hyperon-nucleon and hyperon-hyperon interactions at next-to-leading order in SU(3) baryon chiral perturbation theory extending earlier work by the Bonn-Juelich group.…
Relativistic SU(3) chiral baryon-baryon Lagrangian up to order q^2
Stefan Petschauer, Norbert Kaiser
We construct the most general chiral effective Lagrangian for baryon-baryon contact interactions in flavor SU(3) up to order q^2 using a covariant power counting. A subset of these…
Hyperon-nucleon interaction at next-to-leading order in chiral effective field theory
J. Haidenbauer, S. Petschauer, N. Kaiser +3
Results for the Lambda N and Sigma N interactions obtained at next-to-leading order in chiral effective field theory are reported. At the order considered there are contributions f…
