The Neural Network First-Level Hardware Track Trigger of the Belle II Experiment

S. BÃ¤hr, H. Bae, J. Becker +21

We describe the principles and performance of the first-level ("L1") hardware track trigger of Belle II, based on neural networks. The networks use as input the results from the st…

Tests of light-lepton universality in angular asymmetries of $B^{0} \to D^{*-} ℓ I^½$ decays

Belle II Collaboration, I. Adachi, K. Adamczyk +416

We present the first comprehensive tests of light-lepton universality in the angular distributions of semileptonic $B^{0}$ -meson decays to charged spin-1 charmed mesons. We measure f…

The Physics of the B Factories

A. J. Bevan, B. Golob, Th. Mannel +2003

This work is on the Physics of the B Factories. Part A of this book contains a brief description of the SLAC and KEK B Factories as well as their detectors, BaBar and Belle, and da…

Revisiting the Westerlund 2 Field with the H.E.S.S. Telescope Array

The HESS Collaboration, A. Abramowski, F. Acero +194

Aims. Previous observations with the H.E.S.S. telescope array revealed the existence of extended very-high-energy (VHE; E>100 GeV) Î³-ray emission, HESS J1023-575, coincident with…

Measurement of the $C P$ asymmetry in $D^{0} \to I ¨ ^{+} I ¨ ^{-} I ¨ ^{0}$ decays at Belle II

Belle II Collaboration, M. Abumusabh, I. Adachi +400

We measure the time- and phase-space-integrated $C P$ asymmetry $A_{C P}$ in $D^{0} \to I ¨ ^{+} I ¨ ^{-} I ¨ ^{0}$ decays reconstructed in $e^{+} e^{-} \to c c ˉ$ events collected by the Belle II experim…

Discovery of extended VHE Î³-ray emission from the vicinity of the young massive stellar cluster Westerlund 1

HESS Collaboration, A. Abramowski, F. Acero +198

Results obtained in very-high-energy (VHE; E > 100 GeV) Î³-ray observations performed with the H.E.S.S. telescope array are used to investigate particle acceleration processes in t…
