Pion model with the Nakanishi Integral Representation for the Bethe-Salpeter amplitudes


  • Prof. Joao Pacheco DE MELO

Primary authors



The pion meson in the present work is describe in the Nakanish Integral representation (NIR), for the Bethe-Salpeter amplitude, combined with the Lattice QCD. The quark mass running is fitted by the Lattice data. The results for the weak decay constant are found to be consistent with the experimental data. Also the valence probabilities and the Light-front distribuitions are explored.
