Exotic atomic nuclei reveal traces of new form of superfluidity

Recent observations of the internal structure of the rare isotope ruthenium-88 shed new light on the internal structure of atomic nuclei, a breakthrough that could also lead to further insights into how some chemical elements ...

Ultra-high energy events key to study of ghost particles

Physicists at Washington University in St. Louis have proposed a way to use data from ultra-high energy neutrinos to study interactions beyond the standard model of particle physics. The 'Zee burst' model leverages new data ...

LHCb explores the beauty of lepton universality

The LHCb collaboration has reported an intriguing new result in its quest to test a key principle of the Standard Model called lepton universality. Although not statistically significant, the finding—a possible difference ...

Taking the temperature of dark matter

Warm, cold, just right? Physicists at the University of California, Davis are taking the temperature of dark matter, the mysterious substance that makes up about a quarter of our universe.

Counting photons is now routine enough to need standards

Since the National Institute of Standards and Technology (NIST) built its first superconducting devices for counting photons (the smallest units of light) in the 1990s, these once-rare detectors have become popular research ...

Leptons help in tracking new physics

Electrons with 'colleagues'—other leptons—are one of many products of collisions observed in the LHCb experiment at the Large Hadron Collider. According to theorists, some of these particles may be created in processes ...
