Description
PandaX-4T is a multi-tonne-scale dark matter direct searching experiment, utilizing 3.7 tonne liquid xenon as target material in sensitive volume. The experiment is located at China Jinping Underground Laboratory, with overburden of 2400 meter water equivalent. In this talk, a search of the coherent elastic neutrino-nucleus scatterings induced by the solar $^8$B neutrinos using PandaX-4T data will be reported. Combining two data channels covering an energy region of about 0.4~1.2keV, a signal significance of 2.6$\sigma$ is obtained. The best-fit solar $^8$B neutrino flux is (8.4+-3.1)$\times$10$^6$ cm$^{-2}$s$^{-1}$, consistent with the standard solar model
