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

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

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, ...

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 ...

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 ...

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.

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 ...

Modern industrial processes require measurement solutions that deliver uncompromising accuracy across diverse and challenging conditions. Two primary technologies dominate the high-performance segment ...

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 ...
