Study of and by initial state radiation method at Belle Open
The processes e+e-→ς0ς¯0 and e+e-→ς+ς¯- are studied using initial-state-radiation events in a sample of 980 fb-1 collected with the Belle detector at the KEKB asymmetric-energy e+e- collider. The cross sections from the mass threshold to 3…

Multi-view Semantic Consistency based Information Bottleneck for Clustering Open
Multi-view clustering can make use of multi-source information for unsupervised clustering. Most existing methods focus on learning a fused representation matrix, while ignoring the influence of private information and noise. To address th…

Exploring the intrinsic energy resolution of liquid scintillator to approximately 1 MeV electrons Open
We propose a novel method for exploring the intrinsic energy resolution of a liquid scintillator (LAB + 2.5 g/L PPO + 3 mg/L bis-MSB) to approximately 1 MeV electrons. With the help of coincidence detection technology, single-energy electr…

$R$ measurement and QCD studies at future super $τ-c$ factory Open
We review status of $R$ measurement and QCD studies at low energy range, discuss prospects for a super $τ-$charm factory in $2-7$ GeV. With a high-luminosity $e^+e^-$ collider, statistics are no longer problem for $R$ measurement and a pre…
