Forward dispersion relations and Roy equations in ππ scattering
We review results of an analysis of ππ interactions in S, P and D waves for two-pion effective mass from threshold to about 1.4 GeV. In particular we show a recent improvement of this analysis above the KK̄ threshold using more data for phase shifts and including the S0 wave inelasticity from ππ → KK̄. In addition, we have improved the fit to the f2(1270) resonance and used a more flexible P wave...
متن کاملA global fit of ππ and πK elastic scattering in ChPT with dispersion relations
We apply the one-loop results of the SU (3) L × SU (3) R ChPT su-plemented with the inverse amplitude method to fit the available experimental data on ππ and πK scattering. With esentially only three parameters we describe accurately data corresponding to six differ-(1/2, 1). In addition we reproduce the first resonances of the (1, 1) and (1/2, 1) channel with the right mass corresponding to th...
متن کاملThe pion-pion scattering amplitude. III: Improving the analysis with forward dispersion relations and Roy equations
We complete and improve the fits to experimental ππ scattering amplitudes, both at low and high energies, that we performed in the previous papers of this series. We then verify that the corresponding amplitudes satisfy analyticity requirements, in the form of partial wave analyticity at low energies, forward dispersion relations (FDR) at all energies, and Roy equations belowK̄K threshold; the f...
متن کاملIntegral and derivative dispersion relations , analysis of the forward scattering data
Integral and derivative dispersion relations, analysis of the forward scattering data. Abstract. Integral and derivative dispersion relations (DR) are considered for the forward scattering pp and ¯ pp amplitudes. A new representation for the derivative DR, valid not only at high energy, is obtained. The data on the total cross sections for pp(¯ pp) interaction as well as the data on the paramet...
متن کاملPrecise analysis of ππ scattering data from Roy equations and forward dispersion relations
We review our recent analysis of ππ scattering data in terms of Roy equations and Forward Dispersion Relations, and present some preliminary results in terms of a new set of oncesubtracted coupled equations for partial waves. The first analysis consists of independent fits to the different ππ channels that satisfies rather well the dispersive representation. In the second analysis we constrain ...
