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…

The pion-pion scattering amplitude. III: Improving the analysis with forward dispersion relations and Roy equations
R. Kaminski, J. R. Pelaez, F. J. Yndurain
We complete and improve the fits to experimental scattering amplitudes, both at low and high energies, that we performed in the previous papers of this series. We then verify…
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…
Theory of interstitial oxygen in silicon and germanium
Emilio Artacho, Felix Yndurain
The interstitial oxygen centers in silicon and germanium are reconsidered and compared in an analysis based on the first-principles total-energy determination of the potential-ener…
