We propose to search for light $U(1)$ dark photons, $A$, produced via kinetically mixing with ordinary photons via the Compton-like process, $gamma e^- rightarrow A e^-$, in a nuclear reactor and detected by their interactions with the material in the active volumes of reactor neutrino experiments. We derive 95% confidence-level upper limits on $epsilon$, the $A$-$gamma$ mixing parameter, $epsilon$, for dark-photon masses below 1$sim$MeV of $epsilon~< ~1.3times 10^{-5}$ and $epsilon~<~2.1times 10^{-5}$, from NEOS and TEXONO experimental data, respectively. This study demonstrates the applicability of nuclear reactors as potential sources of intense fluxes of low-mass dark photons.
The experimental bound on lifetime of nu_3, the neutrino mass eigenstate with the smallest nu_e component, is much weaker than those of nu_1 and nu_2 by many orders of magnitude to which the astrophysical constraints apply. We argue that the future r
In the next 10 years medium baseline reactor neutrino experiments will attempt to determine the neutrino mass hierarchy and to precisely measure {theta}_12. Both of these determinations will be more reliable if data from identical detectors at distin
A possible manifestation of an additional light gauge boson $A^prime$, named as Dark Photon, associated with a group $U(1)_{rm B-L}$ is studied in neutrino electron scattering experiments. The exclusion plot on the coupling constant $g_{rm B-L}$ and
We study non-standard interactions (NSIs) at reactor neutrino experiments, and in particular, the mimicking effects on theta_13. We present generic formulas for oscillation probabilities including NSIs from sources and detectors. Instructive mappings
The relatively large measured value of $theta_{13}$ has opened up the possibility of determining the neutrino mass hierarchy through earth matter effects. Amongst the current accelerator-based experiments only NOvA has a long enough baseline to obser
