Recent Developments in Chiral Unitary Dynamics of Resonances
E. Oset, L. S. Geng, D. Gamermann +6
In this talk I summarize recent findings made on the description of axial vector mesons as dynamically generated states from the interaction of peseudoscalar mesons and vector meso…
The WA3 data and the two resonances
L. S. Geng, E. Oset, L. Roca +1
Recent studies based on unitary chiral perturbation theory (UPT) found that the low-lying axial vector mesons can be dynamically generated due to the interaction of the pseudosc…
Scalar radius of the pion and two photons into two pions. Strong S-wave final state interactions
J. A. Oller, L. Roca, C. Schat
The quadratic pion scalar radius, <r^2>^π_s, plays an important role for present precise determinations of ππscattering. The solution of the Muskhelishvili-Omnès equations for the…
Improved dispersion relations for γγ\to π^0π^0
Jose A. Oller, Luis Roca, Carlos Schat
We perform a dispersive theoretical study of the reaction γγ\to pi^0π^0 emphasizing the low energy region. The large source of theoretical uncertainty to calculate the γγ\toπ^0π^0…
Scalar radius of the pion and zeros in the form factor
Jose A. Oller, Luis Roca
The quadratic pion scalar radius, \la r^2\ra^π_s, plays an important role for present precise determinations of ππscattering. Recently, Ynduráin, using an Omnès representation of t…
Meson-Baryon Effective Chiral Lagrangians at O(q^3) Revisited
Jose Antonio Oller, Joaquim Prades, Michela Verbeni
After our work was published, Frink and Meißner \cite{FM06} pointed out that our {\cal O}(q^3) three-flavour meson-baryon chiral Lagrangian was not minimal. Here, we discuss their…
