Searching for Lorentz Violation with Reactor Antineutrinos

Neutrino oscillations are a sensitive probe of Lorentz violation. The Double Chooz neutrino oscillation experiment's exploration of this phenomenon is presented. Sensitivity to Lorentz violation is provided through a search for a sidereal modulation of the observed signal. The extracted measurements represent the first limits on a number of Lorentz violating parameters; specifically, the parameters associated with transitions between electron and tau flavor. This analysis is the first test of Lorentz invariance using a reactor-based antineutrino source.
