A decade-long investigation into puzzling neutrino behavior has now ruled out one of the most widely discussed explanations: the sterile neutrino.

"Precision in these measurements is critical, as even subtle discrepancies could signal deviations from the model — ...

A new theory for the origins of dark matter suggests that fast-moving, neutrino-like dark particles could have decoupled from ...

Scientists from Japan have revealed a new idea explaining why there is matter in the universe, while antimatter has almost ...

For a long time, astronomers have noticed that stars rotate too quickly at the edges of galaxies, as if a hidden mass were ...

Scientists at CERN’s Large Hadron Collider (LHC) have for the first time observed a fundamental asymmetry in the behavior of baryons, the particles that form the bulk of all visible matter. The ...

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 ...

SuperKamiokande: could the detector find evidence for the X? (Courtesy: Kamioka Observatory, Institute for Cosmic Ray Research, University of Tokyo) Physicists in the US and Canada have proposed a new ...

The discovery of a new subatomic particle that is likely the elusive Higgs boson — a particle thought to give all other matter its mass — could be an important step toward uncovering the invisible ...

Dark matter could be made of particles that each weigh almost as much as a human cell and are nearly dense enough to become miniature black holes, new research suggests. While dark matter is thought ...

The current Standard Model of particle physics begins to unravel when probed much beyond the range of current particle accelerators. So no matter what the Large Hadron Collider finds, it is going to ...
