Rare decays of b hadrons provide a powerful way of identifying contributions from physics beyond the Standard Model, in particular from new hypothetical particles too heavy to be produced at colliders. The most relevant experimental measurements are reviewed and possible interpretations are briefly discussed.
The Belle detector at the KEKB electron-positron collider has collected approximately 800 million Upsilon(4S) events in its decade of operation. The KEKB group has proposed Super-KEKB, an upgrade of KEKB to increase the luminosity by two orders of magnitude during a three-year shutdown, with an ultimate goal of 8E35/cm^2/s luminosity. To exploit the increased luminosity, an upgrade of the Belle detector has been proposed. A new international collaboration Belle-II, is being formed, with a broader participation of European institutes. Super-KEKB and Belle-II were officially placed on the KEK 5-year Roadmap in early 2008. The paper presents physics motivation, basic methods of the accelerator upgrade, as well as key improvements of the detector. More details are given on the DEPFET pixel detector that will be completely built in Europe.
A new data acquisition program for personal computers with Windows operating system has been built at Charles University van de Graaff laboratory. It allows fast data acquisition from CAMAC and other PC interface cards using interrupt or polling mode via several types of crate controllers, basic on-line analysis and visualization of acquired data in graphs and histograms. The program is written in combination of MSVC++ and ROOT macros and offers easy customization to individual user requirements via external configuration files, without need of recompilation. In the presented paper a detailed description of the program concepts and features is given. Program was extensively tested with several combinations of hardware and software, and results of the tests are shown at the end.
