Physicists are eyeing charged gravitinos—ultra-heavy, stable particles from supergravity theory—as possible Dark Matter ...

According to the model, dark matter may have started as particles that were hot, light, massless, and fast. As the universe ...

Particle physics has always proceeded in two ways, of which new particles is one. The other is by making very precise measurements that test the predictions of theories and look for deviations from ...

As a physicist working at the Large Hadron Collider (LHC) at Cern, one of the most frequent questions I am asked is “When are you going to find something?” Resisting the temptation to sarcastically ...

CHICAGO (CBS) -- A powerful new particle accelerator that could be set up at Fermilab, a telescope to observe the oldest light in the universe, and research to learn more about mysteries such as dark ...

Particle physics continues to probe the most fundamental constituents of matter while dark matter research seeks to illuminate the unseen mass that permeates our Universe. Recent efforts have ...

Ten years ago, scientists announced the discovery of the Higgs boson, which helps explain why elementary particles (the smallest building blocks of nature) have mass. When you purchase through links ...

UC Santa Cruz physicist Stefano Profumo has put forward two imaginative but scientifically grounded theories that may help solve one of the biggest mysteries in physics: the origin of dark matter. In ...

The Standard Model of particle physics does a decent enough job of explaining the universe, but it still has some holes in it. Now, a new study outlines how one hypothetical particle, the axion, may ...

The standard model of particle physics is often illustrated as a simple grid showing the 17 basic particles (shown above). But an alternative way of visualising it reveals the complex rules that ...

An underground vat of liquid xenon in Italy may have just detected a new particle, born in the heart of the sun. If that's indeed what happened, it could upend laws of physics that have held fast for ...
