Abstract

In this paper, we first discuss the detection of supernova neutrino on Earth. Then we propose a possible method to acquire information about $\theta_{13}$ smaller than $1.5^\circ$ by detecting the ratio of the event numbers of different flavor supernova neutrinos. Such an sensitivity cannot yet be achieved by the Daya Bay reactor neutrino experiment.
