AMoRE: Collaboration for searches for the neutrinoless double-beta decay of the isotope of 100Mo with the aid of 40Ca100MoO4 as a cryogenic scintillation detector

The AMoRE (Advanced Mo based Rare process Experiment) Collaboration is planning to employ ⁴⁰Ca¹⁰⁰MoO₄ single crystals as a cryogenic Scintillation detector for studying the neutrinoless double-beta decay of the isotope ¹⁰⁰Mo. A simultaneous readout of phonon and scintillation signals is performed in order to suppress the intrinsic background. The planned sensitivity of the experiment that would employ 100 kg of ⁴⁰Ca¹⁰⁰MoO₄ over five years of data accumulation would be T _1/2 ^0ν = 3 × 10²⁶ yr, which corresponds to values of the effective Majorana neutrino mass in the range of 〈m _ν 〉 ～ 0.02–0.06 eV.
