  74. 27. Lorentz invariance violation sensitivity in T2HK experiment
    Mr Benjamin Quilain (Ecole Polytechnique, Laboratoire Leprince-Ringuet, In2p3)
    The Lorentz invariance violation (LV) arises at Planck scale, as a consequence of merging standard model and gravity. Though LV effects are naturally highly supressed at low energy, possible measurable effects are predicted in sensitive channels as neutrino oscillations. In this channel, LV operates both by modifying the PMNS oscillations at far detector, but also predicting new oscillations...
