Machine-Learning-Based Waveform Discrimination in the Front-End Electronics of the Belle II Central Drift Chamber for Cross-Talk Noise Reduction
Yun-Tsung Lai, Taichiro Koga, Yu Nakazawa +2
Machine learning (ML) inference on FPGAs has been widely adopted in real-time triggering of collider experiments for detector signature identification. In contrast, the ML applicat…
Real-time graph neural networks on FPGAs for the Belle II electromagnetic calorimeter
I. Haide, M. Neu, Y. Unno +19
We present the development and evaluation of a real-time Graph Neural Network-based trigger module for the electromagnetic calorimeter of the Belle~II experiment at the SuperKEKB c…
Recent developments in data reconstruction for aerogel RICH at Belle II
Luka Santelj
In the forward end-cap of the Belle II spectrometer, particle identification is provided by a proximity focusing RICH detector with an aerogel radiator (ARICH). The ARICH's primary…
The trigger slow control system of the Belle II experiment
C. -H. Kim, Y. Unno, B. G. Cheon +16
The Belle II experiment at the SuperKEKB collider in KEK, Japan, started physics data-taking with a complete detector from early 2019 with the primary physics goal of…
Intermodular Configuration Scrubbing of On-detector FPGAs for the ARICH at Belle II
R. Giordano, Y. Lai, S. Korpar +5
On-detector digital electronics in High-Energy Physics experiments is increasingly being implemented by means of SRAM-based FPGA, due to their capabilities of reconfiguration, real…
Performance of the Unified Readout System of Belle II
Mikihiko Nakao, Ryosuke Itoh, Satoru Yamada +24
The Belle II experiment at the SuperKEKB collider at KEK, Tsukuba, Japan has successfully started taking data with the full detector in March 2019. Belle II is a luminosity frontie…
PCI-express based high-speed readout for the BelleII DAQ upgrade
Q. D. Zhou, S. Yamada, P. Robbe +18
Belle II is a new-generation B-factory experiment, dedicated to exploring new physics beyond the standard model of elementary particles in the flavor sector. Belle~II started data-…
Performance evaluation of the aerogel RICH counter for the Belle II spectrometer using early beam collision data
M. Yonenaga, I. Adachi, L. Burmistrov +32
The Aerogel Ring Imaging Cherenkov (ARICH) counter serves as a particle identification device in the forward end-cap region of the Belle II spectrometer. It is capable of identifyi…
