摘　　要：The neutral kaon meson mixing plays an important role in the test of the Standard Model （SM） and new physics beyond it. Scale invariant unparticle physics induces a flavor changing neutral current （FCNC） transition of m K^0-^-K^0 oscillation at the tree level. In this study, we investigate the scale invariant unparticle physics effects on the m K^0-^-K^0 mixing. Based on the current experimental data, we give constraints of m K0-K0 mixing on the unparticle parameters.The neutral kaon meson mixing plays an important role in the test of the Standard Model （SM） and new physics beyond it.
