DESCRIPTION:Speakers: SeungCheon Kim (CUP\, IBS)\nNeutrinoless double beta
  decay search is a powerful tool to clarify the nature of neutrino as a Di
 rac or Majorana-type particle and probe the unknown neutrino mass. \nObse
 rving this decay means  the lepton number violating process\, which wi
 ll help us understand the baryon asymmetric universe with the leptogenesis
  scenario. \nThe AMoRE collaboration has been searching for neutrinoless 
 double beta decay of 100Mo with cryogenic calorimeters using scintillating
  molybdate crystals and MMC (metallic magnetic calorimeter) sensors. AMoRE
 -pilot and AMoRE-I phases of the experiment demonstrated the competitive p
 otential for the search and the experiment is rapidly moving toward the AM
 oRE-II phase\, which will exploit 100 kg of 100Mo isotopes ultimately.  
 The AMoRE-II detector will consist of hundreds of cryogenic calorimeters a
 nd surrounding muon veto detectors made up of an array of plastic scintill
 ators and water cherenkov detector. The material for the detector system h
 as been carefully chosen and radiation shielding structure has been optimi
 zed to reach the background level of 10^-4 cnts/kg/keV/year around the reg
 ion of the interest for the signal search. The new experiment will be buil
 t in Yemilab\, the new underground laboratory located 1000 meter below Yem
 i mountain in Gangwon province\, South Korea\, which allows the large spac
 e and utilities for the experiment with significantly improved sensitivity
 . The recent result of AMoRE-I new limit and the overall status of the A
 MoRE-II experiment will be presented in the conference.\n\nhttps://indico.
