Polarized generalized parton distributions and structure functions of the <math><mi>ρ</mi></math> meson

The ρ meson polarized generalized parton distribution functions, its structure functions g1 and g2 and its axial form factors G˜1,2 are studied based on a light-front quark model for the first time. Comparing our obtained moments of g1 to the lattice QCD calculation, we find that our results are reasonably consistent to the lattice predictions.
