Résumé :
In the last years there is a growing interest on the semiclassical chiral fermions. But chiral model has no manifest Lorentz symmetry. It is, for the free case, possible to embed the chiral fermion model into Souriau's relativistic, massless, spinning particle model by enslaving the spin. Spin enslavement, hence the chiral model is not boost invariant. However this condition can be restored by a Wigner-Souriau translation. The combined transformation yields the "twisted" Lorentz symmetry of chiral model. The study is extended to the finite Lorentz boosts.
