Dynamical spin effects in the pion

Abstract

We take into account dynamical spin effects in the holographic light-front pion wavefunction in order to predict the pion radius, decay constant, the pion electromagnetic and photon-to-pion transition form factors. We report a striking improvement in the description of all data.Comment: 4 pages, 2 figures.
