Constraining new physics scenarios in neutrino oscillations from Daya Bay data

Abstract

We perform for the first time a detailed fit to the ${\bar{\nu }}_e\to {\bar{\nu }}_e$ disappearance data of the Daya Bay experiment to constrain the parameter space of models where sterile neutrinos can propagate in a large compactified extra dimension (LED) and models where non-standard interactions affect the neutrino production and detection (NSI). We find that the compactification radius $R$ in LED scenarios can be constrained at the level of $0.57\mu m$ for normal ordering and of $0.19\mu m$ for inverted ordering, at 2$\sigma$ confidence level. For the NSI model, reactor data put a strong upper bound on the parameter ${\epsilon }_{ee}$ at the level of $\sim 10^{-3}$, whereas the main effect of ${\epsilon }_{e\mu }$ and ${\epsilon }_{e\tau }$ is a worsening of the determination of ${\theta }_{13}$.
