Until now, all experiments have been unable to detect the mysterious dark matter. All? Not quite. The DAMA experiment has been providing reliable signals for more than 20 years. The problem: To speak of a discovery in science, signals of dark matter have to be confirmed in other experiments. With a…

First hand research: In February and March, three particle physics courses will be held for high-school students. On these days, participants will learn about research methods, identify elementary particles in particle collisions, and “visit” experiments at an observatory on La Palma, at the…

The search for neutrinoless double-beta decay continues with new LEGEND experiment

Final results and completion of the GERDA experiment

The GERDA experiment designed to prove the existence of neutrinoless double beta decay is coming to an end. The research collaboration has now evaluated the full data set produced by the experiment and published it in Physical Review Letters. Even though no signal was found, all goals set for the…

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…

Germawide week of particle physics from 2-8 November - activities at the Max Planck Institute for Physics

Week of particle physics: Roundtrip through the world of elementary particles

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…

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…

The mystery of neutron stars

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…
