Abstract
The advanced molybdenum-based rare process experiment (AMoRE) aims to search for neutrinoless double beta decay (0 nu beta beta) of 100Mo with similar to 100<mml:mspace width="0.166667em"></mml:mspace>kg of 100Mo-enriched molybdenum embedded in cryogenic detectors with a dual heat and light readout. At the current, pilot stage of the AMoRE project we employ six calcium molybdate crystals with a total mass of 1.9kg, produced from 48Ca-depleted calcium and 100Mo-enriched molybdenum (48deplCa100MoO4). The simultaneous detection of heat(phonon) and scintillation(photon) signals is realized with high resolution metallic magnetic calorimeter sensors that operate at milli-Kelvin temperatures. This stage of the project is carried out in the Yangyang underground laboratory at a depth of 700m. We report first results from the AMoRE-Pilot 0 nu beta beta search with a 111 kg day live exposure of 48deplCa100MoO4 crystals. No evidence for 0 nu beta beta decay of 100Mo is found, and a upper limit is set for the half-life of 0 nu beta beta of 100Mo of T1/20 nu</mml:msubsup>>9.5x1022<mml:mspace width="3.33333pt"></mml:mspace>years at 90% C.L. This limit corresponds to an effective Majorana neutrino mass limit in the range <mml:msub>m beta beta <=(1.2-2.1)<mml:mspace width="0.166667em"></mml:mspace>eV
