For nearly a hundred years, every known particle in the universe belonged to one of two camps. Bosons, like photons, can ...

Physicists at CERN’s Large Hadron Collider have uncovered new hints that certain particle decays may not behave as the ...

CHICAGO (CBS) -- A powerful new particle accelerator that could be set up at Fermilab, a telescope to observe the oldest light in the universe, and research to learn more about mysteries such as dark ...

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

Dark matter particles could be mediators of the interaction between electrons and atomic nuclei, as shown by a study ...

UC Santa Cruz physicist Stefano Profumo has put forward two imaginative but scientifically grounded theories that may help solve one of the biggest mysteries in physics: the origin of dark matter. In ...

Professor of Theoretical Physics Risto Paatelainen from the University of Turku in Finland has spent nearly ten years working on a single unanswered question in particle physics. He aims to find out ...

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

Particle and high energy physics seeks to understand the fundamental constituents of matter and the interactions that govern them across the smallest distance scales and highest energies. The Standard ...
