Real-time Graph Building on FPGAs for Machine Learning Trigger Applications in Particle Physics
Marc Neu, Juergen Becker, Philipp Dorwarth +4
We present a design methodology that enables the semi-automatic generation of a hardware-accelerated graph building architectures for locally constrained graphs based on formally d…
Physics reach of a long-lived particle detector at Belle II
Sascha Dreyer, Torben Ferber, Anastasiia Filimonova +9
We have studied three realistic benchmark geometries for a new far detector GAZELLE to search for long-lived particles at the \superkekb accelerator in Tsukuba, Japan. The new dete…
Multi-Modal Track Reconstruction using Graph Neural Networks at Belle II
Lea Reuter, Tristan Brandes, Giacomo De Pietro +1
High backgrounds and detector ageing impact the track finding in the Belle II central drift chamber, reducing both track purity and track efficiency in events. This necessitates th…
Dark Higgs Bosons at Colliders
Torben Ferber, Alexander Grohsjean, Felix Kahlhoefer
The Large Hadron Collider (LHC) has confirmed the Higgs mechanism to be responsible for generating mass in the Standard Model (SM), making it attractive to also consider spontaneou…
Identification of light leptons and pions in the electromagnetic calorimeter of Belle II
Anja Novosel, Abtin Narimani Charan, Luka Å antelj +3
The paper discusses new method for electron/pion and muon/pion separation in the Belle II detector at transverse momenta below 0.7 , which is essential for efficien…
Hardware-Aware Design of a GNN-Based Hit Filtering Algorithm for the Belle II Level-1 Trigger
Greta Heine, Fabio Mayer, Marc Neu +2
The Belle~II experiment operates at high luminosity, where an increasing beam-induced background imposes stringent demands on the hardware Level-1 trigger system, which must operat…
