The new calculation, made at the Large Hadron Collider (LHC) near Geneva, could help solve a niggling mystery about this ...

The LHCb experiment has taken a leap in precision physics at the Large Hadron Collider (LHC). In a new paper submitted to Physical Review Letters and currently available on the arXiv preprint server, ...

For a few years, one of particle physics’ most unsettling numbers seemed to be pointing somewhere strange. The trouble ...

Measurement of W boson particle mass confirms Standard Model of physics and reignites the search for other particles.

When fundamental particles are heavier or lighter than expected, physicists' understanding of the universe can tip into the unknown. A particle that is just beyond its predicted mass can unravel ...

Scientists at the Institute of Modern Physics (lMP) of the Chinese Academy of Sciences (CAS) and their collaborators have demonstrated the effectiveness of an innovative nuclear mass measurement ...

In nuclear physics, "magic numbers" identify specific numbers of protons or neutrons that lead to especially stable nuclei. Recognizing these numbers helps scientists better understand the structure ...

Molecular ion spectroscopy and mass measurements constitute a dynamic field where experimental finesse meets rigorous theory to unravel fundamental aspects of molecular structure and interactions.

Astronomers have, for the first time, pinned down both the mass and distance of a planet that drifts through the galaxy without a parent star, turning a once purely theoretical class of worlds into a ...

At the University of Oxford, Justin Benesch studies assemblies made between proteins called molecular chaperones and the proteins they protect in cells. These assemblies slow the formation of amyloid ...

In a milestone that could impact the future of physics, researchers have managed to place an upper mass limit on the subatomic particle called the neutrino. Without knowledge of the mass possessed by ...
