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

A neglected force produced by neutrinos and other particles helps atomic physics measurements align with predictions of the ...

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

Physicists have re-measured the mass of the W boson, and are happy to report it’s an almost perfect fit with theoretical ...

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

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 ...

Wondering whether whether Dark Matter particles actually are produced inside a jet of standard model particles, led researchers to explore a new detector signature known as semi-visible jets, which ...

In 1930, a young physicist named Carl D. Anderson was tasked by his mentor with measuring the energies of cosmic rays—particles arriving at high speed from outer space. Anderson built an improved ...

Researchers at the Max Planck Institute for Quantum Optics (MPQ), Garching, in collaboration with Prof. Dr. Randolf Pohl from the Institute for Physics at Johannes Gutenberg University Mainz (JGU), ...
