Report of the Working Group on Goldstone Bosons
Johan Bijnens, Ada Farilla, Rory Miskimen
An overview is presented of the talks in the working group on Goldstone Bosons. Topics touched on are CP-violation in the Kaon system, rare Kaon decays, -scattering, -meson…
The S-wave Λπphase shift is not large
Ulf-G. Meißner, José Antonio Oller
We study the strong interaction S-wave Λπphase shift in the region of the Ξmass in the framework of a relativistic chiral unitary approach based on coupled channels. All parameters…
Chiral dynamics in the presence of bound states: kaon-nucleon interactions revisited
J. A. Oller, Ulf-G. Meißner
We study the S-wave kaon-nucleon interactions for strangeness S=-1 in a novel relativistic chiral unitary approach based on coupled channels. Dispersion relations are used to perfo…
Pion and Kaon Vector Form Factors: a Chiral Unitary Approach
J. E. Palomar, J. A. Oller, E. Oset
The pion and kaon coupled-channel vector form factors are described by making use of the resonance chiral Lagrangian results together with a suitable unitarization method in order…
Pion and Kaon Vector Form Factors
J. A. Oller, E. Oset, J. E. Palomar
We develop a unitarity approach to consider the final state interaction corrections to the tree level graphs calculated from Chiral Perturbation Theory () allowing the inclusi…
Scalar Mesons and Chiral Symmetry
J. A. Oller
It is the purpose of the present manuscript to emphasize those aspects that make the scalar sector with vacuum quantum numbers rather unique. Chiral symmetry is the basic tool for…
