KamLAND-Zen searches for a possible conversion of anti-matter (anti-neutrino) to matter (neutrino) in a very rare process called neutrinoless double beta decay. In this experiment a large amount of Xenon-136 gas is being added into the sensitive part of detector volume of the world’s largest liquid scintillator detector KamLAND (hence the name KamLAND-Zen). The latest phase of this experiment was started in May 2018. After completion in August 2018 this detector called KamLAND-Zen 800 (800kg of Xenon-136 are being used) has become by far the largest and most sensitive neutrinoless double beta decay experiment in the world.
