Hyperon non-leptonic decays in relativistic Chiral Perturbation Theory with resonances

Nora Salone, Fernando Alvarado, Stefan Leupold +1

Motivated by recent experimental advances in the corresponding measurements, non-leptonic hyperon decays are calculated, for the first time in a relativistic manner, in Chiral Pert…

Photon-fusion reactions from the chiral Lagrangian with dynamical light vector mesons

I. V. Danilkin, M. F. M. Lutz, S. Leupold +1

We study the reactions $γ γ \to π^{0} π^{0}$ , $π^{+} π^{-}$ , $K^{0} K ˉ^{0}$ , $K^{+} K^{-}$ , $η η$ and $π^{0} η$ based on a chiral Lagrangian with dynamical light vector mesons as formulated wit…

Electromagnetic transitions in an effective chiral Lagrangian with the eta-prime and light vector mesons

C. Terschlusen, S. Leupold, M. F. M. Lutz

We consider the chiral Lagrangian with a nonet of Goldstone bosons and a nonet of light vector mesons. The mixing between the pseudoscalar mesons eta and eta-prime is taken into ac…
