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. 000150442 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttps://creativecommons.org/licenses/by/4.0/deed.es 000150442 590__ $$a4.189$$b2007 000150442 591__ $$aPHYSICS, MULTIDISCIPLINARY$$b8 / 68 = 0.118$$c2007$$dQ1$$eT1 000150442 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000150442 700__ $$aGamboa, J. 000150442 700__ $$aMéndez, F. 000150442 700__ $$aDas, Ashok 000150442 700__ $$0(orcid)0000-0002-2868-194X$$aLópez-Sarrión, J. 000150442 773__ $$g650, 5-6 (2007), 401-406$$pPhys. lett., Sect.
