Precise determination of the f0(500) and f0(980) parameters in dispersive analysis of the pipi data
R. Kaminski, R. Garcia-Martin, J. R. Pelaez +1
We review the use of new and precise dispersive equations, which also implement crossing symmetry, in order to shed further light on the long-standing puzzle in the parameters of t…
Precise determination of the f0(600) and f0(980) pole parameters from a dispersive data analysis
R. Garcia-Martin, R. Kaminski, J. R. Pelaez +1
We use our latest dispersive analysis of pion-pion scattering data and the very recent Kl4 experimental results to obtain the mass, width and couplings of the two lightest scalar-i…
The pion-pion scattering amplitude. IV: Improved analysis with once subtracted Roy-like equations up to 1100 MeV
R. García- Martín, R. Kamiński, J. R. Peláez +2
We improve our description of pion-pion scattering data by imposing additional requirements to our previous fits, in the form of once-subtracted Roy-like equations, while extending…
MO analysis of the high statistics Belle results on with chiral constraints
R. Garcia-Martin, B. Moussallam
We reconsider Muskhelishvili-Omnès (MO) dispersive representations of photon-photon scattering to two pions, motivated by the very high statistics results recently released by the…
Once subtracted Roy-like dispersion relations and a precise analysis of scattering data
R. Garcia-Martin, R. Kaminski, J. R. Pelaez +1
We report our progress on the data analysis of scattering data in terms of Forward Dispersion Relations (FDR), as well as Roy equations (RE) and their once-subtracted counterp…
Once and twice subtracted dispersion relations in the analysis of pi pi amplitudes
R. Kaminski, R. Garcia-Martin, J. R. Pelaez +1
Once and twice subtracted crossing symmetric dispersion relations applied to scattering data are analyzed and compared. Both sets of dispersion relations can be used to…
In memory of Paco Yndurain: A precise determination of pion-pion scattering from experiment and dispersion relations
J. R. Pelaez, R. Garcia-Martin, R. Kaminski +1
This talk is dedicated to the memory of Paco Yndurain, the original speaker in the conference. After a short account of his scientific career, we briefly review our ongoing collabo…
Precise dispersive data analysis of the f0(600) pole
R. Garcia-Martin, R. Kaminski, J. R. Pelaez
We review how the use of recent precise data on kaon decays together with forward dispersion relations (FDR) and Roy's equations allow us to determine the sigma resonance pole posi…
Precise determination of the sigma pole location from a dispersive analysis
R. Garcia-Martin, R. Kaminski, J. R. Pelaez
We review how the use of recent precise data on kaon decays together with forward dispersion relations (FDR) and Roy's equations allow us to determine the sigma resonance pole posi…
Precise analysis of pion-pion scattering data from Roy equations and forward dispersion relations
J. R. Pelaez, R. Garcia-Martin, R. Kaminski +1
We review our recent analysis of pion-pion scattering data in terms of Roy equations and Forward Dispersion Relations, and present some preliminary results in terms of a new set of…
Experimental status of the isoscalar S wave at low energy: pole and scattering length
F. J. Yndurain, R. Garcia-Martin, J. R. Pelaez
The experimental results obtained in the last few years on kaon decays (K and, above all, Ke4 decays) allow a reliable, model independent determination of low energy sc…
