Abstract: The description of the neutrino evolution in matter has become crucial in the determination of most of the remaining uncertainties in the neutrino oscillation framework. Such is the case of CP violation phase or the mass ordering. In the presence of non-standard interaction
(NSI) of the neutrino with the matter, the determination of the oscillation parameters would be altered. In this talk, I am going to present the latest bound on these new interactions obtained by using all the available data from oscillation experiments and in combination with the results on coherent neutrino-nucleus scattering. In this work, it is study the robustness of the three neutrino mixing scenario in the presence of NSI, and the LMA-D solution. The results obtained are robust under the broad spectrum of up-to-down strengths found in the neutrino propagation along the Sun and the Earth.
