Description

ZICOS is a one of future experiments for neutrinoless double beta decay using ${}^{96}$Zr nuclei. In order to achieve sensitivity over ${10}^{27}$ years, ZICOS will use tons of ${}^{96}$Zr, and need to remove ${}^{208}$Tl background events as observed by KamLAND-Zen one order of magnitude. For this purpose, we have developed new technique to distinguish the signal and background using a topology of Cherenkov light. In order to demonstrate this method, we are planning to observe about 100 ${}^{96}$Zr two neutrino emission double beta decay events per year using 1 little of ZICOS liquid scintillator containing 0.4 g of ${}^{96}$Zr filled in 2$\nu$-ZICOS detector. Here, we will report a present status of this experiment which will start the observation in this summer.
