Title: Search for a time-varying electron antineutrino signal at Daya Bay

Abstract

A search for a time-varying ¯νe signal was performed with 621 days of data acquired by the Daya Bay Reactor Neutrino Experiment over 704 calendar days. The time spectrum of the measured ¯νe flux normalized to its prediction was analyzed with a Lomb-Scargle periodogram, which yielded no significant signal for periods ranging from 2 hours to nearly 2 years. The normalized time spectrum was also fit for a sidereal modulation under the Standard Model Extension (SME) framework to search for Lorentz and CPT violation (LV-CPTV). Limits were obtained for all six flavor pairs ¯e¯μ,¯e¯τ, ¯μ¯τ, ¯e¯e,¯μ¯μ and ¯τ¯τ by fitting them one at a time, constituting the first experimental constraints on the latter three. As a result, Daya Bay’s high statistics and unique layout of multiple directions from three pairs of reactors to three experimental halls allowed the simultaneous constraint of individual SME LV-CPTV coefficients without assuming others contribute negligibly, a first for a neutrino experiment.
