Neutrinos don’t seem to get their mass in the same way as other particles in the Standard Model. In 1998, researchers made a discovery that challenged their understanding of particle physics and ...

Rubin Observatory will bring new capabilities to the studies of dark matter and dark energy. In just a few years, scientists at Vera C. Rubin Observatory in Chile will launch the Legacy Survey of ...

Once the most popular framework for physics beyond the Standard Model, supersymmetry is facing a reckoning—but many researchers are not giving up on it yet. The Standard Model of particle physics is ...

The fundamental particle of light is both ordinary and full of surprises. What physicists refer to as photons, other people might just call light. As quanta of light, photons are the smallest possible ...

The average banana produces a particle of antimatter roughly once every 75 minutes. US-based scientists and students working on research and experiments with the Large Hadron Collider contribute to a ...

Meet the short-lived particle that helps the sun shine. Visible matter is made from only a handful of particles, but many more are behind the scenes, affecting what those matter particles do. The W ...

Matter and antimatter behave differently. Scientists hope that investigating how might someday explain why we exist. One of the great puzzles for scientists is why there is more matter than antimatter ...

The answer has to do with dark matter’s role in shaping the cosmos. Half a century after Vera Rubin and Kent Ford confirmed that a form of invisible matter—now called dark matter—is required to ...

A large and unexpected excess of top quark pairs has the physics community excited, but the interpretation is still up for debate. In 1995, Alexander Grohsjean cut out a story from the local German ...

Scientists don’t yet know what dark matter is made of, but they are full of ideas. Although nearly a century has passed since an astronomer first used the term “dark matter” in the 1930s, the elusive ...

The 2013 documentary Particle Fever follows physicists from the start-up of the LHC through the discovery of the Higgs boson. Where are those physicists now? Physicist Monica Dunford remembers when ...

Something is out there. As far as scientists know, just 15% of the matter in the universe is the ordinary kind we can see. The other 85%, called dark matter, remains beyond detection, invisibly ...
