Towards foundation-style models for energy-frontier heterogeneous neutrino detectors via self-supervised pretraining

Abstract Accelerator-based neutrino physics is entering an energy-frontier regime in which interactions reach the tera-electronvolt scale and produce exceptionally dense, overlapping detector signatures. Event interpretation is impractical for conventional reconstruction and chal...

Volatile depletion in rocky planets as a chemical fingerprint of hybrid accretion

Volatile depletion in rocky planets records their formation history. Earth and Mars grew through different hybrid pathways of pebble and planetesimal accretion, providing a new way to interpret the diversity of rocky planets beyond the Solar System.

Design and Commissioning of a Deuterium-Tritium Gas Delivery System for Muon-Catalyzed Fusion in a Diamond Anvil Cell

We report the design, commissioning, and operation of deuterium-deuterium (DD) and deuterium-tritium (DT) gas delivery systems developed to load a diamond anvil cell (DAC) beam target for muon-catalyzed fusion (µCF). The DAC approach enables DT fuel to be compressed to gigapascal...
