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 ...

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 ...

A professor at the University of Tennessee reimagines the way we teach STEM with a science-fiction story-based class. In the beginning, a spaceship called the Yggdrasil is sailing through the cosmos ...

Just over 40 years ago, a new theory about the early universe provided a way to tackle multiple cosmological conundrums at once. For Alan Guth, insight into the origins of the universe started in a ...

Scientists in the particle physics community are bringing environmental and climate issues to the table in discussions about future research. Using a particle collider requires a lot of energy. For ...

The LHCb experiment at CERN has revealed a fundamental asymmetry in the behavior of particles called baryons. “The reason why it took longer to observe CP violation in baryons than in mesons is down ...

Scientists have learned a lot about the Higgs boson in the decade since they discovered it. But intriguing questions remain. When the news came, on July 4, 2012, it moved some scientists to tears.

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 ...

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 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 ...

Three physicists share their experiences learning and communicating physics in a foreign language: English. Rose Ferreira, an astronomer and popular-science communicator who goes by the name Rose DF, ...

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, ...
