A surprising and rare particle decay has left scientists puzzled as kaons, particles made up of quarks, are decaying in ways that defy current physics models. Could this anomaly indicate the existence ...

Something odd is happening deep inside the data streams from CERN’s Large Hadron Collider. A set of “forbidden” patterns in how unstable particles decay, combined with rare Higgs events and a ...

Why did this particle mysteriously disintegrate?

Add Yahoo as a preferred source to see more of our stories on Google. If dark matter particles decay, then scientists could hunt for signs of this process, including X-ray or gamma-ray radiation or ...

Scientists just announced that they have detected a completely unexpected number of antihelium particles—something that could mean they were generated by dark matter. Specifically, they could have ...

For the first time, scientists observe a new and rare decay mode where oxygen-13 breaks into three helium nuclei and a proton following beta decay. Scientists have previously observed interesting ...

It may be that the famous Higgs boson, co-responsible for the existence of masses of elementary particles, also interacts with the world of the new physics that has been sought for decades. If this ...

In a random moment, all energy is lost. The unstable subject cannot help but decay, slowly but surely, letting go of particles to become stable. It loses itself to become balanced again. This is a ...

Do kaons decay using a new kind of physics? Researchers are trying to explain their anomalous findings. Their larger experiment is an ongoing investigation of CP symmetry. The anomalies could be ...

"WIMPs are still the leading candidate for dark matter, but billions of dollars of experiments have been done, only getting stronger and stronger upper limits, so alternative scenarios have to be ...
