Performance evaluation of GYGAG crystals for neutrinoless double beta decay search
Hibiki Hayasaki, Keishi Hosokawa, Koichi Ichimura +6
Neutrinoless double beta decay (0) is a crucial for confirming neutrinos' Majorana characteristics. Previous searches for 0 decay of Gd using GSO crystals w…

Probing Internal Conversion and Dark-Matter-Induced De-excitation of 180mTa with a gamma-ray TES Array
A. Gando, K. Ichimura, K. Ishidoshiro +5
We propose and evaluate a source-as-detector search for the de-excitation of the long-lived isomer in natural tantalum (Ta), using a -ray transiti…

Development of an early warning method incorporating pre-supernova neutrino light curves
Keita Saito, Minori Eizuka, Zhuojun Hu +9
Massive stars () emit neutrinos known as pre-supernova (pre-SN) neutrinos through thermal and nuclear interactions for cooling the stellar core during the fina…
