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 ...

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 ...

Brazilian physicist César Lattes, considered a national hero for his discoveries, paved the way for trailblazing research projects in particle astrophysics across Latin America and beyond. When César ...

For decades scientists have tried to find a way to measure the mass of the lightest matter particle known to exist. Three new approaches now have a chance to succeed. In 1980, Hamish Robertson was a ...

In 2023, the ALICE experiment was ready for their best year yet, until a mysterious signal threatened everything. As the LHC wraps up its 2025 lead-ion run, physicists recall how they worked together ...

The Large Synoptic Survey Telescope will be named for an influential astronomer who left the field better than she found it. The Large Synoptic Survey Telescope, a flagship astronomy and astrophysics ...

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 ...

Hadrons count among their number the familiar protons and neutrons that make up our atoms, but they are much more than that. In the early 1900s, physicists were trying to find the source of a ...

Scientists are exploring a variety of ways to make quantum bits. We may not need to settle on a single one. The goal of building a quantum computer is to harness the quirks of quantum physics to solve ...

Over time, particle physics and astrophysics and computing have built upon one another’s successes. That coevolution continues today. In the mid-twentieth century, particle physicists were peering ...

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 ...

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 ...
