A neural network z-vertex trigger for Belle II
We present the concept of a track trigger for the Belle II experiment, based on a neural network approach, that is able to reconstruct the z (longitudinal) position of the event vertex within the latency of the first level trigger. The trigger will thus be able to suppress a large fraction of the dominating background from events outside of the interaction region. The trigger uses the drift tim...
متن کاملBelle II early physics program of bottomonium spectroscopy
The Belle II experiment at the SuperKEKB collider is a major upgrade of the KEK "B factory" facility in Tsukuba, Japan. Phase 1 commissioning of the main ring of SuperKEKB has started in February 2016 and first physics data will be recorded in 2017 during the so-called Phase 2 commissioning, when the partial Belle II detector will be operated still without its vertex detector. In 2018, the full...
متن کاملgauge - boson production from LFV τ decays at Belle II
proposed that such a light gauge boson can be detected at the Belle II experiment with a luminosity of 50 ab−1 by the e+e− → γ + / E process through the kinetic mixing with the photon, where the missing energy / E is from the Z ′ → ν̄ν decays. We study the phenomenological implications when a pair of singlet vector-like leptons carrying different Lμ −Lτ charges are included, and a complex single...
متن کاملThe Belle Collaboration
We report the first observation of the decay B → χc0K using 21.3 fb of data collected by the Belle detector at the Υ(4S) resonance. The preliminary result for the branching fraction is B(B → χc0K) = (8.0 −2.4 ± 1.0 ± 1.1) × 10 where the first error is statistical, the second is systematic, and the third comes from the uncertainty in the χc0 → ππ branching fraction. Typeset using REVTEX
متن کاملThe Belle Silicon Vertex Detector
The silicon vertex detector of the Belle experiment has been built to provide the vertex information of B meson decays at the KEKB accelerator. It consists of three cylindrical layers of double sided, double metal silicon sensors read out by VA1 chips. The analog signals are transmitted to a system of fast analog-to-digital converters and are reduced on a system based on Motorola Digital Signal...
