Abstract

We investigate the elastic form factors of the ρ meson in the light-front quark-model (LFQM). We find that only the helicity 0→0 matrix element of the plus current receives the zero-mode contribution. After taking care of the zero-mode issue, we obtain the magnetic (μ) and quadrupole (Q) moments of the ρ meson as μ = 1.92 and Q = 0.43, respectively.
