Reconstruction as a Bridge for Event-Based Visual Question Answering
Hanyue Lou, Jiayi Zhou, Yang Zhang +4
Integrating event cameras with Multimodal Large Language Models (MLLMs) promises general scene understanding in challenging visual conditions, yet requires navigating a trade-off b…
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 in…
GPS-Synchronized Monitoring of Core-collapse Supernova Bursts with PandaX-4T via Coherent Elastic Neutrino Nuclear Scattering
Binyu Pang, Zihao Bo, Wei Chen +108
The landmark detection of neutrinos from SN1987A marked the dawn of neutrino astrophysics. The neutrino burst provided essential insights into fundamental properties of neutrinos,…
Precise Measurement of Po Half-life with Exact Parent-daughter Pairing in PandaX-4T
PandaX Collaboration, Chenxiang Li, Zihao Bo +108
We report a precise measurement of half-life using the PandaX-4T liquid xenon time projection chamber (TPC). , emanating from a calibr…
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…
Position reconstruction and surface background model for the PandaX-4T detector
Zhicheng Qian, Linhui Gu, Chen Cheng +100
We report the position reconstruction methods and surface background model for the PandaX-4T dark matter direct search experiment. This work develops two position reconstruction al…
