The experiment's third and final result, based on the last three years of data, is in perfect agreement with previous results ...

With big outstanding questions and little hints of new physics, physicists are now rethinking some of their most fundamental ...

The Standard Model is a kind of periodic table of the elements for particle physics. But instead of listing the chemical elements, it lists the fundamental particles that make up the atoms that make ...

Project Poltergeist led to the discovery of the ghostly particle. Sixty years later, scientists are confronted with more neutrino mysteries than ever before. In 1930, Wolfgang Pauli proposed the ...

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 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 ...

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 ...

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 ...

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 ...

Not a curve in sight, as far as the eye can see. Mathematicians, scientists, philosophers and curious minds alike have guessed at the shape of our universe. There are three main options to choose from ...

The Standard Model is far more than elementary particles arranged in a table. The Standard Model of particle physics is often visualized as a table, similar to the periodic table of elements, and used ...
