[en] The pion electromagnetic form factor is calculated with a light-front quark model. The 'plus' and 'minus' components of the electromagnetic current are used to calculate the electromagnetic form factor in the Breit frame with two models for the q q-bar vertex. The light-front constituent quark model describes very well the hadronic wave functions for pseudo-scalar and vector particles. Symmetry problems arising in the light-front approach are solved by the pole dislocation method. The results are compared with new experimental data and with other quark models. (author)
