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 ...
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 ...
A possible explanation for the lightness of neutrinos could help answer some big questions about the universe. Mass is a fundamental property of matter, but there’s still a lot about it we don’t ...
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 ...
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 ...
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 ...
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 ...
A team of young scientists paused their new physics searches to develop an innovative machine-learning tool, which is now helping them narrow in on a rare and messy decay of the Higgs boson. Physicist ...
Advance your romance with science. This Valentine’s Day, we challenged our readers to send us physics-inspired love poems. You answered the call: We received dozens of submissions—in four different ...
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 ...
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 ...
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 ...
