CERN: Most precise measurement of mass and charge of Light Nuclei and Snti-Nuclei. Why did anti-matter disappear almost completely from our universe, whereas matter did not? Scientists are attempting to solve this mystery at the European research institute at CERN. Now they published the most precise measurement of the properties of light atomic nuclei and anti-nuclei ever made.

At the LHC, researchers let lead nuclei and protons collide at the highest beam energies to date. The temperatures created are 100,000X higher than those in the center of the Sun. “A state is created that is very similar to the one after the Big Bang,” explains Prof Laura Fabbietti...
