Alpha-clustered hypernuclei and chiral SU(3) dynamics
Emiko Hiyama, Yasuro Funaki, Norbert Kaiser +1
Light hypernuclei with an cluster substructure of the core nucleus are studied using an accurate cluster approach (the Hyper-THSR wave function) in combination with a density-d…
Single-particle potential from resummed ladder diagrams
Norbert Kaiser
A recent work on the resummation of fermionic in-medium ladder diagrams to all orders is extended by calculating the complex single-particle potential for m…
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…
