Beyond Half-Life Limits: Robust Operator-Level Interpretation of Multi-Isotope Neutrinoless Double-Beta Decay
K. Ishidoshiro
Current and future neutrinoless double-beta decay () searches are usually characterized by half-life limits or projected sensitivities. For operator-level interpretation,…
Search for Diffuse Supernova Neutrino Background in the Full KamLAND Dataset with Neural-Network-Based Event Classification
D. Chernyak, T. Eda, M. Eizuka +63
We report a search for the diffuse supernova neutrino background (DSNB) with the KamLAND detector, targeting electron antineutrinos via inverse beta decay in the neutrino energy ra…
Search for Majorana Neutrinos with the Complete KamLAND-Zen Dataset
S. Abe, T. Araki, K. Chiba +69
We present a search for neutrinoless double-beta () decay of Xe using the full \mbox{KamLAND-Zen 800} dataset with 745\,kg of enriched xenon, corresponding to an e…
Constraints on Fermionic Dark Matter Absorption from Radiochemical Solar-Neutrino Measurements
K. Ishidoshiro, K. Tachibana
We reinterpret classic radiochemical solar-neutrino measurements as ``rate meters'' for additional, non-negative capture-like contributions induced by fermionic dark matter absorpt…
Machine Learning on Heterogeneous, Edge, and Quantum Hardware for Particle Physics (ML-HEQUPP)
Julia Gonski, Jenni Ott, Shiva Abbaszadeh +118
The next generation of particle physics experiments will face a new era of challenges in data acquisition, due to unprecedented data rates and volumes along with extreme environmen…
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…
