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 ...

As technology improves, scientists discover new ways to search for theorized dark matter particles called axions. In the early 1970s, physics had a symmetry problem. According to the Standard Model, ...

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 ...

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 ...

Our best model of particle physics explains only about 5 percent of the universe. The Standard Model is a thing of beauty. It is the most rigorous theory of particle physics, incredibly precise and ...

The Planck scale sets the universe’s minimum limit, beyond which the laws of physics break. In the late 1890s, physicist Max Planck proposed a set of units to simplify the expression of physics laws.

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 ...

In the 1900s, Albert Einstein unified the concepts of space and time, giving us a useful new way to picture the universe. At the start of the 20th century, physicists had a problem: The speed of light ...

A forthcoming upgrade to the IceCube detector will provide deeper insights into the elusive particles. Underneath the vast, frozen landscape of the South Pole lies IceCube, a gigantic observatory ...

The stuff of daily existence is made of atoms, and all those atoms are made of the same three things: electrons, protons and neutrons. Protons and neutrons are very similar particles in most respects.

Amy Catanzano bridges the worlds of poetry and science. In April 2018, Amy Catanzano sat in her loaned office at the Simons Center for Geometry and Physics at Stony Brook University in New York, ...

The mysterious particle could hold the key to why matter won out over antimatter in the early universe. Almost every particle has an antimatter counterpart: a particle with the same mass but opposite ...
