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…
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…
