The experiment ran from to The Belle detector was located at the collision point of the asymmetric-energy electron — positron collider , KEKB. The experiment was motivated by the search for CP-violation. The KEKB accelerator was the world's highest luminosity machine at the time. The instantaneous luminosity exceeded 2.

The Belle II experiment is a particle physics experiment designed to study the properties of B mesons heavy particles containing a beauty quark and other particles. Many interesting analyses of the Belle and BaBar experiments were limited by statistical uncertainties, which was the main motivation to build a new generation of B-factory - Belle II. The physics program of Belle II includes the studies of the following particles or processes: [7]. The majority of the Belle II dataset will be recorded at Upsilon 4S center-of-mass energy, while a small portion of it will be taken at Upsilon 5S and as energy scans. Belle II is a general purpose high-energy particle detector with almost full solid angle coverage. The detector is asymmetric in beam direction, because the initial energy of the electron beam is larger than the positron beam. Much of the original Belle detector has been upgraded [4] to cope with the higher instantaneous luminosity provided by the SuperKEKB accelerator. The main components are the following, from the innermost to the outermost systems. The Belle II experiment data taking is separated into three phases: [14]. The collaboration handles the collision data recorded at the experiment, performs the data analysis and delivers the results in form of scientific journal articles, conference talks, etc. As on October 5, , it included 1, members from institutes and 27 countries around the globe. This is the main package used to simulate, reconstruct and analyse the recorded collision events at the Belle II experiment and there are several other separate satellite packages, used for DAQ , computation of the systematic uncertainties, etc. To coordinate the software development, the Belle II Collaboration uses industrial collaboration tools such as Atlassian Jira , Confluence and git -based BitBucket service.

Site Navigation. Tracking particle smashups and detector conditions from half a world away, scientists seek answers to big physics mysteries. A key part of the experiment is taking place half a world away, using computing resources and expertise at the U. The study of the decay process transformation into other lighter particles of heavy flavor mesons has established that matter and antimatter behave differently. Additional sources of matter-antimatter asymmetry must exist and, if observed, could indicate that some new, previously undiscovered particles might be taking part in the action. To identify such unobserved phenomena, scientists must analyze many times more heavy flavor meson decays than have ever been produced at past electron-positron facilities. Belle II will accumulate more than 50 times the data sample of the original Belle experiment at KEK, which itself produced million such events. Japan's flagship electron-positron collider, SuperKEKB, achieved the world's highest instantaneous luminosity for a colliding-beam accelerator. To keep collision rates high, the electron and positron beams that circulate inside SuperKEKB must be tightly focused. But the magnetic fields guiding the particles in one beam can have unwanted effects in the adjacent beam, causing the particles to spread.

Call us Syllabus: Science and Technology. The Large Hadron Collider is a giant, complex machine built to study particles that are the smallest known building blocks of all things. Latest upgrade: After its maintenance and upgrades, the collider was switched back on this April. How will it help us to understand the evolution of the universe? What is the significance of this observation?
