Electromagnetic structure and weak decay of pseudoscalar mesons in a light-front QCD-inspired model
arXiv:hep-ph/0507336 · doi:10.1140/epja/i2005-10246-4
Abstract
We study the scaling of the meson mass splitting and the pseudoscalar weak decay constants with the mass of the meson, as seen in the available experimental data. We use an effective light-front QCD-inspired dynamical model regulated at short-distances to describe the valence component of the pseudoscalar mesons. The experimentally known values of the mass splittings, decay constants (from global lattice-QCD averages) and the pion charge form factor up to 4 [GeV/c] are reasonably described by the model
