from the where's-Z'-Boson? dept.

Arthur T Knackerbracket has found the following story:

The Belle II experiment has been collecting data from physical measurements for about one year. After several years of rebuilding work, both the SuperKEKB electron–positron accelerator and the Belle II detector have been improved compared with their predecessors in order to achieve a 40-fold higher data rate.

Scientists at 12 institutes in Germany are involved in constructing and operating the detector, developing evaluation algorithms, and analyzing the data.

The Max Planck Institute for Physics, the Semiconductor Laboratory of the Max Planck Society, the Ludwigs-Maximilians-Universität and the Technical University of Munich made leading contributions to the new development of the highly sensitive innermost detector, the Pixel Vertex Detector and the software for analyzing the data.

With the help of Belle II, scientists are looking for traces of new physics that can be used to explain the unequal occurrence of matter and anti-matter and the mysterious dark matter.

One of the so far undiscovered particles that the Belle II detector is looking for is the Z′ boson – a variant of the Z boson, which acts as an exchange particle for the weak interaction.

As far as we know, about 25 percent of the universe consists of dark matter, whereas visible matter accounts for just under 5 percent of the energy budget. Both forms of matter attract each other through gravity.

Dark matter thus forms a kind of template for the distribution of visible matter. This can be seen, for example, in the arrangement of galaxies in the universe.

    "As far as we know Abra-Cadabra, about 25 percent of the universe consists of dark matter,"

    We do not KNOW this: it is one 'theory'. God's...get it right.

      Obviously can't be TOO redundant: these idiots keep SAYING it!

      Sheesh!
