Probing scalar-neutrino and scalar-dark-matter interactions with PandaX-4T
PandaX Collaboration, Tao Li, Zihao Bo +113
Scalar-mediated interactions may exist among neutrinos, dark matter particles, or between the two. Double -decay experiments provide a powerful tool to probe such exotic intera…
A Control Architecture for Training-Free Memory Use
Yanzhen Lu, Muchen Jiang, Zhicheng Qian +1
Prompt-injected memory can improve reasoning without updating model weights, but it also creates a control problem: retrieved content helps only when it is applied in the right sta…
State Transfer Reveals Reuse in Controlled Routing
Yanzhen Lu, Zhicheng Qian, Muchen Jiang +1
Prompt-based interventions can change model behavior, but trained success alone does not identify where the behaviorally relevant state is represented. We study this question in co…
Precise Xe Double Beta Decay Measurement in PandaX-4T with Implications on the Nuclear Matrix Elements and Majorons
PandaX Collaboration, Zhe Yuan, Zihao Bo +111
The continuous spectrum of double beta decay () provides a sensitive probe to test the predictions of the standard model and to search for signatures of new physics beyond it…
Search for Light Dark Matter with 259-day data in PandaX-4T
Minzhen Zhang, Zihao Bo, Wei Chen +108
We present a search for light dark matter particles through their interactions with atomic electrons and nucleons, utilizing PandaX-4T data with an effective exposure of 1.04 tonne…
Tomographic beta-gamma spectroscopy of nuclear beta decay
PandaX Collaboration, Zhe Yuan, Zihao Bo +111
Nuclear decay, a sensitive probe of nuclear structure and weak interactions, has become a precision test bed for physics beyond the Standard Model, driven by recent advances i…
