A gauge invariant chiral unitary framework for kaon photo- and electroproduction on the proton
B. Borasoy, P. C. Bruns, Ulf-G. Meißner +1
We present a gauge invariant approach to photoproduction of mesons on nucleons within a chiral unitary framework. The interaction kernel for meson-baryon scattering is derived from…
eta, eta-prime --> pi+ pi- l+ l- in a chiral unitary approach
B. Borasoy, R. Nißler
The decays eta, eta-prime --> pi+ pi- l+ l- (with l = e, mu) are investigated within a chiral unitary approach which combines the chiral effective Lagrangian with a coupled-channel…
On the extraction of the quark mass ratio (m_d - m_u)/m_s from Gamma(eta' -> pi^0 pi^+ pi^-)/Gamma(eta' -> eta pi^+ pi^-)
B. Borasoy, Ulf-G. Meißner, R. Nißler
The claim that the light quark mass ratio (m_d - m_u)/m_s can be extracted from the decay width ratio Gamma(eta' -> pi^0 pi^+ pi^-)/Gamma(eta' -> eta pi^+ pi^-) is critically inves…
K^- p scattering length from scattering experiments
B. Borasoy, U. -G. Meißner, R. Nißler
The strong K^- p scattering length is extracted within chiral SU(3) unitary approaches from a very large variety of fits to low-energy K^- p scattering data. Very good overall agre…
Comment on "Surprises in threshold antikaon-nucleon physics"
B. Borasoy, R. Nissler, W. Weise
It has recently been claimed by Oller et al. [PRL 95 (2005) 172502] that the DEAR kaonic hydrogen data can be reconciled with K^- p scattering data in a chiral unitary approach. In…
Decays of eta and eta-prime within a chiral unitary approach
B. Borasoy, R. Nissler
Various decays of eta and eta-prime are investigated within the framework of U(3) chiral effective field theory in combination with a relativistic coupled-channels approach. Final…
