The Daya Bay and T2K results on sin22θ13 and non-standard neutrino interactions

We show that the relatively large best fit value of sin^22θ13=0.14(0.17) measured in the T2K experiment for fixed values of i) the Dirac CP violation phase δ=0, and ii) the atmospheric neutrino mixing parameters θ(23)=π/4, |Δm^2(32)|=2.4×10^{−3} eV^2, can be reconciled with the Daya Bay result sin^22θ(13)=0.090±0.009 if the effects of non-standard neutrino interactions (NSI) in the relevant ν ̄e→ν ̄e and νμ→νe oscillation probabilities are taken into account. © 2014 The Authors.
