Photon-photon scattering, pion polarizability, and chiral symmetry.
Recent attempts to detect the pion polarizability via analysis of γγ → ππ measurements are examined. The connection between calculations based on dispersion relations and on chiral perturbation theory is established by matching the low energy chiral amplitude with that given by a full dispersive treatment. Using the values for the polarizability required by chiral symmetry, predicted and experi...
متن کاملPion - Pion Scattering Information
We show how the reaction e-e’+ n-n’y can be used to study the dipion system in states of even charge conjugation (and even angular momentum). In particular, its utility for experimentally investigating an I = 0, J = 0 resonance (e-meson) is discussed in detail. (Submitted to Phys. Rev. ) * Work supported by the U. S.

متن کاملPion-pion Scattering above Resonances
We model large angle intermediate energy pion-pion scattering by the pQCD two-gluon (2g) exchange contribution and discuss the onset of the dominance of the Glauber-Gribov-Landshoff (GGL) component. The pQCD 2g exchange contribution becomes substantial already at |t| ∼ 1 GeV, but the pQCD exchange dominance is deferred to |t| ∼ 3 GeV because of competing multiple soft rescattering effects. Base...
متن کاملThe pion-pion scattering amplitude
We obtain reliable ππ scattering amplitudes consistent with experimental data, both at low and high energies, and fulfilling appropriate analyticity properties. We do this by first fitting experimental low energy (s ≤ 1.42GeV) phase shifts and inelasticities with expressions that incorporate analyticity and unitarity. In particular, for the S wave with isospin 0, we discuss in detail several se...
متن کاملPion–pion scattering at low energy
We present technical details of the evaluation of the elastic ππ scattering amplitude to two loops in chiral perturbation theory. In particular, we elaborate on the renormalization procedure at the two–loop order and on the evaluation of the relevant Feynman diagrams that can all be expressed in terms of elementary functions. For the sake of clarity, we discuss these matters both in the N–compo...
