| Research Abstract |
Dark Matter is one of the biggest problems in our universe, however, whose existence is supported by several observations. Many of direct dark matter search experiments are undergoing and one group reported the annual modulation due to dark matter signal, although this result was excluded by several experiments. The difference rate in summer and winter is a few percent. The goal of this study is to establish more robust signature of dark matter signal by using different detector materials that enables us to see more than two times difference in the rate and the study supports this possibility in the future.
