We investigate the electromagnetic form factors of the (rho) meson in light cone QCD sum rules. We find that the ratio of the magnetic and charge form factors is larger than two at all values of Q^2, (Q^2 >= 0.5 GeV^2). The values of the individual form factors at fixed values of Q^2 predicted by the light cone QCD sum rules are quite different compared to the results of other approaches. These results can be checked in future, when more precise data on (rho) meson form factors is available.

Next-to-leading-order time-like rho electromagnetic form factors in ${k_{\rm T}}$ factorization
The NLO time-like rho meson electromagnetic form factors are obtained by analytic continuation of space-like NLO results, with twist-3 contributions dominating and predictions consistent with BABAR.
