  Violation of Lorentz invariance and CPT symmetry is a predicted phenomenon of
Planck-scale physics. Various types of data are analyzed to search for Lorentz
violation under the Standard-Model Extension (SME) framework, including
neutrino oscillation data. MiniBooNE is a short-baseline neutrino oscillation
experiment at Fermilab. The measured excesses from MiniBooNE cannot be
reconciled within the neutrino Standard Model; thus it might be a signal of new
physics, such as Lorentz violation. We have analyzed the sidereal time
dependence of MiniBooNE data for signals of the possible breakdown of Lorentz
invariance in neutrinos. In this brief review, we introduce Lorentz violation,
the neutrino sector of the SME, and the analysis of short-baseline neutrino
oscillation experiments. We then present the results of the search for Lorentz
violation in MiniBooNE data. This review is based on the published result
(ArXiv:1109.3480).
