Physicists know that their elegant theoretical description of forces and particles – the Standard Model – must be incomplete, ...

Physicists have determined the mass of the W boson with the highest precision yet by analysing more than a billion proton ...

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

Two independent lines of evidence from the world’s most powerful particle experiments are converging on the same uncomfortable conclusion: something is producing signals that the Standard Model of ...

Researchers at ETH Zurich (Eidgenössische Technische Hochschule Zürich), along with teams from Germany and Australia, have made some incredibly precise measurements using calcium atoms—and the results ...

Researchers at the University of Ottawa suggest that if the fundamental strengths of nature's forces, such as gravity, change gradually over time and across various regions of space, this could ...

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), ...
