TL;DR: In this article, the neutrino-less double beta decays (0νββ) of 100Mo were made by means of ELEGANT V. Most stringent lower limits on the half-lives for the ground-state transition were obtained for the 0νβα processes as T 1 2 0ν (m ν ) > 5.2 × 10 22 y, T 1 1 2 ε (λ) > 3.9 × 1022 y and T 1 two ε(ε)-ε (δ)-δ ≥ 5.1

TL;DR: In this paper, the inelastic peak of spin-coupled dark matter was precisely analyzed and the peak spread and shift due to the recoil momentum was precisely estimated by Monte Carlo simulation.
Abstract: Axial-vector (spin-coupled) excitation of 127 I by inelastic scattering of dark matter (DM) was studied to search for spin-coupled DM. In the present work, the inelastic peak was precisely analyzed. The peak spread and shift due to the recoil momentum was precisely estimated by Monte Carlo simulation. A new stringent limit on the spin-coupled DM was obtained.

TL;DR: In this paper, the neutrino-less double beta decays (0vββ) of 100Mo were made by means of ELEGANT V. Most stringent lower limits on the half-lives were obtained for the 0vβα ground state transition as T1/20v(mv) > 5.2 × 1022y.
Abstract: Exclusive measurements of neutrino-less double beta decays(0vββ) of 100Mo were made by means of ELEGANT V. Most stringent lower limits on the half-lives were obtained for the 0vββ ground state transition as T1/20v(mv) > 5.2 × 1022y, T1/20v(λ) > 3.9 × 1022y and T1/20v(η) > 5.1 × 1022y, for the mass term 〈mv〉 and the right handed current terms of 〈λ〉 and 〈η〉, respectively. The most stringent lower limit on the 0vββB followed by Majoron(B) was derived as T1/20vB > 5.4 × 1021 y. These lead to the upper limits of 〈mv〉
