We perform a detailed combined fit to the ν ¯ e → ν ¯ e disappearence data of the Daya Bay experiment and the appearance ν μ → ν e and disappearance ν μ → ν μ data of the Tokai to Kamioka (T2K) one in the presence of two models of new physics affecting neutrino oscillations, namely a model where sterile neutrinos can propagate in a large compactified extra dimension and a model where non-standard interactions (NSI) affect the neutrino production and detection. We find that the Daya Bay ⨁ T2K data combination constrains the largest radius of the compactified extra dimensions to be R ≲ 0.17 μ m at 2 σ C.L. (for the inverted ordering of the neutrino mass spectrum) and the relevant NSI parameters in the range O ( 10 − 3 ) − O ( 10 − 2 ) , for particular choices of the charge parity violating phases.
