Whether axions exist is still up for debate. If they do exist, two open questions in particle physics could be resolved: The puzzle of what dark matter is made of – and the question of why the strong interaction, one of the four known forces in the universe, has a particular characteristic. The…

How was the universe created? What are we made of? What does the “world machine” at CERN investigate? Science enthusiasts can pursue such questions during the Week of the Particle World from 2 to 8 November 2020. All over Germany, the locations of the Particle World Network invite guests to become…

This event will be in German language.

Operation of the Large Hadron Collider (LHC) particle accelerator has been resting since January of 2019. Although “resting” is not quite the right word: During the planned shutdown until early 2022, intensive work is being done on technical improvements – including the ATLAS experiment. The Max…

Neutron stars are probably the most astounding objects in the universe. They are the remnants of supernova explosions. The core of a star collapses under its own gravity thereby squeezing matter in such a way that single atomic nuclei are solved in a soup of nucleic particles - mostly neutrons, but…

In 2019, the MAGIC telescopes detected the first Gamma Ray Burst at very high energies. This was the most intense gamma-radiation ever obtained from such a cosmic object. But the GRB data have more to offer: with further analyses, the MAGIC scientists could now confirm that the speed of light is…

Tailwind for the search for rare particle decays in the Belle II experiment: The SuperKEKB accelerator ring has now achieved the highest luminosity ever measured. The electron-positron accelerator beats not only its predecessor KEKB but also the Large Hadron Collider (LHC) at CERN. This has just…

Following its inauguration in October 2018, the first LST (Large-Sized Telescope) is currently in the commissioning phase. The LST-1 will commence research operations in 2021. But the imposing gamma-ray telescope has already provided an important proof of its performance: It recorded the extremely…

On 19 June 2020 CERN presented the update to the European Strategy for Particle Physics. In an Interview with Der Tagesspiegel Prof Siegfried Bethke from the MPI for Physics explains which technical concepts are under discussion and what the costs might be.
