An eightfold equivalence-preserving speedup of the JUNO OMILREC vertex and energy reconstruction
Guangbao Sun, Qishan Liu, Wenjie Wu +7
The Jiangmen Underground Neutrino Observatory (JUNO) reconstructs each event's vertex and energy with OMILREC, a maximum-likelihood fit that scans all large photomultipl…
Improving the Angular Resolution of IBD Events Using Neutron Capture Information in Super-Kamiokande
Qishan Liu, Kenny C. Y. Ng
One of the most important neutrino interactions is the Inverse Beta Decay (IBD). However, the IBD events typically carry no directional information in water Cherenkov detectors as…
Elastic neutrino-electron scattering perspectives at nuclear reactors
Luis A. Delgadillo, Qishan Liu, Randhir Singh
The determination of the weak mixing angle, , at low momentum transfers remains a powerful test of the Standard Model and its potential new physics extensions. In this…
Measuring the Low-Energy Weak Mixing Angle with Supernova Neutrinos
Chun-Ming Yip, Xu-Run Huang, Ming-chung Chu +1
The weak mixing angle is a fundamental parameter in the electroweak theory with a value running according to the energy scale, and its precision measurement in the low-energ…
Searching for Particle Dark Matter with eROSITA Early Data
Chingam Fong, Kenny C. Y. Ng, Qishan Liu
Many well motivated dark matter (DM) particle candidates can decay into detectable X-ray photons. We analyze the Final Equatorial Depth Survey (eFEDS) data from eROSITA early data…
