Elastic ππ scattering to two loops
We evaluate analytically the elastic scattering amplitude to two loops in chiral perturbation theory and give numerical values for the two S{wave scattering lengths and for the phase shift diierence 0 0 ? 1 1 .
متن کاملThe Inverse Amplitude Method in ππ Scattering in Chiral Perturbation Theory to Two Loops
The inverse amplitude method is used to unitarize the two loop ππ scattering amplitudes of SU(2) Chiral Perturbation Theory in the I = 0, J = 0, I = 1, J = 1 and I = 2, J = 0 channels. An error analysis in terms of the low energy one-loop parameters l̄1,2,3,4, and existing experimental data is undertaken. A comparison to standard resonance saturation values for the two loop coefficients b̄1,2,3,4...
متن کاملError estimates for ππ scattering threshold parameters in Chiral Perturbation Theory to two loops
Using the analysis of ChPT to two loops, we perform an error analysis of the threshold and low energy parameters, based on the uncertainties for the one loop low energy parameters and the resonance saturation mechanism. Different sets of one loop low energy constants have been considered. Thus, the predictive power of the effective field theory is quantified on the basis of the present experime...
متن کاملΠπ Scattering
We demonstrate that, together with the available experimental information , chiral symmetry determines the low energy behaviour of the ππ scattering amplitude to within very small uncertainties. In particular, the threshold parameters of the S–, P –, D– and F –waves are predicted, as well as the mass and width of the ρ and of the broad bump in the S–wave. The implications for the coupling const...
متن کاملTheory of Ππ Scattering
The study of ππ scattering is a classical subject in the field of strong interactions: it is a scattering process that may occur at very low energy, far away from the resonance region, and it only involves the quasi–Goldstone bosons of the chiral symmetry of strong interactions. If we stay at low energy, we could expect its dynamics to be strongly constrained by chiral symmetry: as Weinberg sho...
