Pion distribution amplitude – from theory to data
We describe the present status of the pion distribution amplitude as originated from two sources: (i) a nonperturbative approach, based on QCD sum rules with nonlocal condensates, and (ii) a NLO QCD analysis of the CLEO data on Fγγ ∗π(Q2), supplemented by the E791 data on diffractive dijet production, and the JLab F(pi) data on the pion electromagnetic form factor. 1. PION DISTRIBUTION AMPLITUD...
متن کاملPion distribution amplitude from lattice QCD.
A method is explained through which a pointwise accurate approximation to the pion's valence-quark distribution amplitude (PDA) may be obtained from a limited number of moments. In connection with the single nontrivial moment accessible in contemporary simulations of lattice-regularized QCD, the method yields a PDA that is a broad concave function whose pointwise form agrees with that predicted...

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 کاملγ ∗ γ ( ∗ ) → π transitions and the pion distribution amplitude
We discuss what can be learned about the shape of the pion distribution amplitude from the form factor for γ∗γ(∗) → π transitions.
