TL;DR: In this paper, a finite half-life of T 2v 1 2 =(1.15 + 0.30 − 0.20 )×10 19 yr (68% CL ) for 2νββ decay and the most stringent lower limit of T 0v 1/2 > 4.7 × 10 21 yr ( 68% CL ), for the 0v ββ decay were obtained.

TL;DR: The present Rapid Communication reports the first application of a huge scintillation detector to search for the nonbaryonic dark matter (DM) by investigating directly the elastic scattering of DM by ' I and Na nuclei in the NaI detector.

TL;DR: The ELEctron GAmma-ray NeuTrino Spectrometer V (ELECTRON GATV) as mentioned in this paper was developed primarily for studying rare double-beta decays, and it is a low background high sensitivity detector for low energy beta (β), electron (e), and gamma (γ) decays.

TL;DR: In this paper, the NM-p and mesonic weak-decay pions from Λ produced by the (π+, K+) reaction on 12C have been measured and the results indicate finite polarizations of the relevant Λ-hypernuclei and asymmetric NM weak decays.

TL;DR: In this paper, a finite half-life of T12/2 nu = 1.15-0.30*1019 y (68% CL) for the two neutrino beta beta decay of 100Mo and the most stringent lower limit of T 12/0 nu > 4.1*1023 y by searching for the gamma decay was obtained.
