abstract
The electromagnetic form factors of the $\rho$ meson are evaluated adopting a relativistic constituent quark model based on the light-front formalism, and using a meson wave function with the high-momentum tail generated by the one-gluon-exchange interaction. The breakdown of the rotational covariance for the one-body component of the current operator is investigated and the sensitivity of the ratio of the $\rho$-meson form factors to the pion (charge) form factor to the spin-dependent component of the effective $q \bar{q}$ interaction is illustrated.

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.

$\phi$-meson spectroscopy and diffractive production using two Schr\"odinger like equations on the light-front
A two-equation light-front model reproduces the phi meson mass spectrum and HERA diffractive production cross sections, but underpredicts its decay constant.
