| Popis: | 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 $\rm 0.1~keV/c^2$ 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. Comment: updated with an erratum CHIN. PHYS. LETT. Vol. 38, No. 10 (2021) 109902 |
