A search for solar axions and anomalous neutrino magnetic moment with the complete PandaX-II data

Abstract

We report a search for new physics signals using the low energy electron recoil events in the complete data set from PandaX-II, in light of the recent event excess reported by XENON1T. The data correspond to a total exposure of 100.7 ton-day with liquid xenon. With robust estimates of the dominant background spectra, we perform sensitive searches on solar axions and neutrinos with enhanced magnetic moment. We find that the axion-electron coupling $g_{Ae}<4.6\times 10^{-12}$ for an axion mass less than $0.1keV/{\mathrm{c}}^2$ and the neutrino magnetic moment ${\mu }_{\nu }<4.9\times 10^{-11}{\mu }_B$ at 90% confidence level. The observed excess from XENON1T is within our experimental constraints.
