| Resumo | |
We search for scalar and tensor non-standard interactions using (anti)-electron neutrino disappearance in oscillation data. We found a slight preference for non-zero CP violation, coming from both tensor and scalar interactions. The preference for CP violation is led by Daya Bay low-energy data with a significance that reaches similar to 1.7 sigma in the global analysis (and similar to 2.1 sigma when considering only medium baseline reactors data) compared to the standard neutrino oscillation scenario. In some cases, our results indicate that the atmospheric mass squared difference falls outside the range allowed by accelerator long baseline experiments. This suggests the need for further investigation in future work. (AU) | |
