We show that, for particular choices of the deformation, oscillation between massless neutrino species takes place when only Lorentz invariance is violated. On the other hand, if both Lorentz and CPT invariances are violated, we show that there is no oscillation between massless neutrino species. Comparing with the existing experimental data on neutrino oscillations, we obtain bounds on the parameter for Lorentz invariance violation. info:eu-repo/semantics/openAccess by https://creativecommons.org/licenses/by/4.0/deed.es 4.189 2007 PHYSICS, MULTIDISCIPLINARY 8 / 68 = 0.118 2007 Q1 T1 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Gamboa, J.
