Asia-US-Australia Collaboration in the Silicon Vertex Detector Project for the BELLE High Energy Physics Experiment at KEK

The BELLE detector is the state-of-the-art detector built to investigate CP violating phenomena. The goal is to identify the origin of Charge conjugation Parity Violation (CPV) in B-meson decays--a key to explaining why matter, not anti-matter, dominates the universe. The BELLE detector contains a high-precision particle trajectory detection system, consisting of silicon microstrip sensors. This silicon system contains about 100K channels, which will be read by a high-speed, online data system. All electronic channels must be constantly monitored and calibrated.

The BELLE collaboration consists of 49 institutions from 11 countries (Australia, China, India, Korea, Japan, Philippines, Poland, Russia, Taiwan, Ukraine and USA). The participating institutions will jointly analyze the data generated. The Asia-US-Australia collaboration was formed to design and build the silicon vertex detector. KEK (High Energy Accelerator Research Organization) is located in Japan.
