TL;DR
This study searches for neutrino-antineutrino oscillations caused by Lorentz invariance violation using reactor antineutrino data, setting new limits on related theoretical coefficients.
Contribution
It provides the first experimental limits on 15 coefficients for neutrino-antineutrino mixing within the Standard-Model Extension framework.
Findings
No evidence for neutrino-antineutrino oscillations was observed.
First limits established on 15 coefficients of neutrino-antineutrino mixing.
Results constrain theories involving Lorentz invariance violation.
Abstract
The disappearance of reactor antineutrinos in the Double Chooz experiment is used to investigate the possibility of neutrino-antineutrino oscillations arising due to the breakdown of Lorentz invariance. We find no evidence for this phenomenon and set the first limits on 15 coefficients describing neutrino-antineutrino mixing within the framework of the Standard-Model Extension.
