Testing Quantum Mechanics in Nuetrino Oscillation
  A testing of quantum mechanics in nuetrino oscillation is presented. The quantum mechanics violation motivated by arguements of quantum gravity is investigated in neutrino system. The formula of density matrix and oscillation probability of nuetrinos with and without the effect of quantum mechanics violation are derived for the cases of neutrino ocsillation in vacuum and matter. The limits to the corresponding parameters are obtained from neutrino experiments.
